I had a bum (alcoholic looking guy, a house painter by trade he said) beg for money at a shopping center in Gainesville. Nice new shopping plaza and good area.
He said he was hungry and needed money for food.
I took him to dinner.
He barely touched his food and soda.
He kept saying he needed cash.
When we left, he'd wasted 3/4 of his meal, left on the table.
I'm sure he wanted $ for booze or drugs.
Good for you for trying though.
