It is good to provide support to the homeless
Dave is walking down the street when he's approached by a homeless man, Bill who asks him if he can spare some change.
Dave wants to respond to Bill's question.
Dave tells Bill that he does have some change he can give him.
Dave tells Bill he doesn't have any change and even if he did he doesn't give money to drunks.
Bill is delighted and relieved to get a little bit of money, so he can buy food.
Bill is insulted that Dave assumes he's a drunk and stressed that he won't enough money to buy food today.
