I was passing through Carson City today when I stopped for gas, actually I was running on fumes. A young couple parked next to me asked for gas money. I said sure but let me see your gas guage. He said he didn't think it worked and drove away. Last year a father sent his two young son's over to ask me for money. After I gave him $20 I asked to see his guage and it was 3/4 full. I'm all for helping people but not interested in being taken advantage of. How do you all handle it?
