Did I just get scammed???

Ok, so I was just in line for a train at montgomery and this african american tranny (I think it was a tranny, but a very convincing one) goes down the line asking people if they have a dollar for four quarters. Everyone ignores him/her. I did happen to have a dollar, so I say yes. I give her the dollar and she holds out her hand, which has about $1.50 in various coins. So I take four quarters. She says thanks, then makes some comment like "you got a very nice hard body" which is the reason I think she was a tranny and the reason I feel like this might be some kinda scam. The quarters look real, I still have my wallet, backpack, underwear, etc. Why do I feel so used??? Does anyone know this person?
