These are my kinda threads. With all the nonsense that goes on in STS you begin to wonder where the good natured people are!
I usually go to Burger King and order two of what I'm having and then give the other meal to the first person I see asking for food/money.
I sometimes think about sitting down and eating with them while having a chat but it appears a little pretentious to me. It would appear as if I'm trying to display that I'm kind and I've just donated a burger so I choose to just give the burger and disappear before the person has a chance to take a look at me or say thanks.
I ought to give more though and the moment I have enough income to be comfortable, I'll make a point of giving something daily.
