2 years ago I was at a car show that benefitted cancer research. At one point all the Deloreans did a drive around the fairgrounds. As we were getting ready, a guy asked me if his son (a big Delorean fan) could ride along. Seemed like good people, so I figured "why not".
The kid was awestruck, his folks snapped a bunch of pix, and nice conversation was had by all. At the end of the ride, his uncle insisted on thanking me with some cash. I refused several times, then finally asked him to give it to the cancer charity instead, and he obliged.
I had a nice time at the show, a ride along made a kid's day, and some money went to cancer research. One of many positive experiences I have had with my car(s).
