Ok, I'll chime in.
First rules of survival when threatened. (Physically that is.)
1.) RUN LIKE HELL if you can and just get the FUCK out of the situation. Avoidance at all costs is the first and primary action.
2.) Fight if you must. Be sure to use ANY WEAPON available to you!! Remember, the ONLY Rule in the "Grown Up World" of fighting is to WIN and/or SURVIVE IT!!
Alright OP, it is NOT your job, duty, or responsibility to TEACH anyone anything. PERIOD!!
From your story it "sounds" like the situation got handled correctly without much incident.
So, let it go!!
Now, get on with your life and remember...Dignity doesn't pay the bills or keep YOUR ASS ALIVE!!
P.S. I took Tiger and Preying Mantis style Kung Fu for 6 years while growing up and kick boxed in the ring for 3 years. I then later severed in the United States Marine Corps.
I had a Concealed weapons permit for over 15 years and carried every day.
Only pulled my weapon out twice in that time and NEVER had to fire it!!
I have NOT been in a Physical altercation where "I" fought back in over 25 years now and I'll be 49 next week.. (Two times I have been in places that I should not have and CHOSE to NOT fight back when attacked and only defended. Bloody lip was the worst I got from either incident where I was out numbered at least 5 to 1. Since I was ALONE in those situations, I would have either been DOG PILED and BEATEN BADLY or been arrested due to the testimonies of "The Locals.")
Call me a PUSSY if you want, but even COPS won't cuff/arrest me with less than 4 of them around.
Take what I've said as you will.
Alright.....what the hell?!
In any fight situation you have FOUR things at your disposal or to keep in mind.
1.) Human resources. That would include YOU and any friends with you and your opponent and any friends that they may have.
Now, you should know your own fighting capabilities as well as you friends abilities.
You MUST assume that ALL of your opponents can fight like Jet Lee or Jackie Chan.
2.) Natural resources. Do you have a beer bottle in your hand? Does your opponent? What is near by that you can grab and use quickly? Is there say an Iron Railing or Table near by that you can SMASH them into? Are you near a busy road where you can push them into on coming traffic?
3.) Time. This will be a BIG factor in your strategy. If only 1 of your 3 friends can fight worth a damn along with yourself, then you only have TWO functional weapons and TWO HUMAN SHIELDS for the battle. If the opponent also has 3 friends then you HAVE to assume that it is now your 2 against his 4. This means that you have LESS time to WIN or GET AWAY!!
4.) Space. (Physical surroundings.) Are you in a bar with a bunch of tables around? If so, then KICKS might have to be ruled out. Is the guy near the end of the bar where you could corral him in behind it to RESTRICT his options for fighting back? You get the idea.
Physical fighting 101:
You should always fight in Spheres. (I was taught Circles, but Spheres are more accurate to me.)
Point of Contact Sphere would be grappling. Hands on each other. In this close proximity things like your Shoulder and Head can be used to strike. Stomps where you use the edge of your shoe to RAKE down the shin before CRUSHING bones in the foot. Hands & Hips can be used to take the opponent off balance.
Inner Sphere would be any distance beyond Point and to the length of a right or left cross punch. So, this will encompass using your elbows and knees as well.
The Outer Sphere is where Kicks come in. NEVER....I repeat...NEVER use a kick ABOVE YOUR OWN WAIST HEIGHT!!! Optimally you want to use you kicks in a downward strike so that you can ADD your body weight to the strike and if the opponent moves you aren't left open. Your foot will just travel to the ground and you'll keep your stability.
Knees (The top or side.) are the best target for kicks with ANKLES being the next best and Groin strikes being 3rd.
If you wind up having to Duke it out, as FAST as you can analyze whether the opponent is a Grabber/Tackler (Point Sphere), Puncher (Inner Sphere), or Kicker (Outer Sphere.) and then STAY OUT OF THAT RANGE during the confrontation. Fight from the distance that the opponent is NOT comfortable with.
Grabber: Keep punching and kicking him. Keep him away from you.
Puncher: Kick him or Grab him and take him to the ground.
Kicker: Move in so that he can't use those legs.
A lot of people learn Combos like a jab followed by a left or right cross. Well, say you throw that jab and the opponent steps back, now he is OUT OF THE INNER SPHERE of your upcoming right cross. So, you would NOT throw the right cross but instead use a REVERSE kick of some sort. (Maybe a cross-over side kick. But that would not have as much power.)
If you threw the right or left cross when he stepped back you would now be open to be hit.
If he stepped into you after the jab then an elbow, knee, or take down would be the best bet over the left or right cross.
Your forehead is THE BEST defense of a punch to the face. It's also the FASTEST block available to you.
A finger strike to the eyes if done right can end a fight quickly. An upward palm strike to the nose will SHUT THEIR EYES and flood them with tears. Either of these two strikes could very well give you the time needed to get away from a confrontation. (The Nose strike and putting cartilage into their brain and killing them is a myth.)
A half fist to the throat can also end a fight quick and give you time to get away.
Break the opponent's knee and it should be over as well.
Also, always wear a BELT and keep a pocket knife if possible. They can be of more help than you would imagine.
The keys in the hand with the keys protruding from your hand while walking to your car is NOT just for WOMEN!!
Nor is having Pepper Spray or a Taser device.
