Had a similar experience the other night walking out of Barnes and Noble back to my car. Kind of checked out this cute well-dressed younger girl (maybe 19-22) walking towards me, who smiles, and then before I can pass her, stops and says "excuse me sir...." (kind of awkward since I am only 27 and really look about her age). She told me that she had run out of gas and that her card was overdrawn, and was wondering if I could spare a few dollars. Now I wasn't born yesterday, and this wouldn't be the first time that I have heard this exact story from various people. But I guess I felt bad and figured that if I were her dad, I'd rather her be begging strangers for money to support whatever substance abuse problem she was likely having, rather than using her body to get it. Gave her the couple of dollar bills I had in my pocket, and then pondered her existance for my drive home. I'd like to think that she just legitimately needed some gas, but I doubt that was the case.
