Did i just meet a professional beggar?

This lady came up and asked for money for gas because she said she ran out and she was at her wits end. I had a gas can with 5 gallons and offered to give her some but then she said another person tried to do that but she had the kind of car that doesn't accept gas unless its from a gas station nozzle. But I said we would try anyways and I just had to finish parking my rv because she came up while I was parking. I started finishing parking and she just walked away and left in her car. Wtf was this lol? She had a nice ford pickup and didn't look shabby at all. Was she like a professional beggar? Maybe she thought I wad rich with my rv and would give her more than 5 dollars? Lol
