I'm really skeptical of ATL bums because they act like they have no memory and sometimes have money and still be out there asking for more.
Let me tell what this one bum did about a year ago:
My GF and I drove separate cars to the date and after she had to go to the gas station. I followed her over there. Dude is outside begging for money to buy some food and drink.
I told her to keep it moving but my GF is too nice so she gives dude some money. I'm about 10 feet away like

.
We leave the car at the gas station and walk because she has to go to the bathroom and won't use the gas station. We come back and air is loudly hissing out of one of her tires. I'm just sitting there with the Cosby.
Dude walks back up to us and says "I'm a former mechanic. For $15, I'll change that tire for you"
I look at him

and my GF like

.
It was plainly obvious dude cut her tires and to top it off, there was another car in the gas station parking lot with a flat tire. This dude had the audacity to take advantage of my GF's kindness, slash her tire while we were gone, then ask for more money. I haven't given out money to a homeless person after that. I probably will again one day but these dudes getting bold.
