I wasn't traveling, but had stopped into one of my favorite Thai restaurants for lunch and there was an old couple in the parking lot standing around a car. As I get out of my vehicle, the old man approaches me and asks me if I could give them $5 because their car run out of gas. They happened to have a gas can with them, so I told him to hop in the car and drove him down the street to a gas station, filled up the gas can for him (he conveniently didn't have any money) and drove him back to the restaurant.
After I dumped the gas in his tank, I went into the restaurant and the owner said that old couple had been out there all day trying to get money out of people. I was the only one who took them to a gas station. They didn't really want gas, they wanted money.
