A few weeks ago I went to our local quick shop to get a soda & off on the far side of the parking lot was a classic car with the hood up. The guy was looking the car over as if he were having trouble. I drove over & ask if he was ok & he said he was loosing oil from somewhere. There wasn't a lot of oil on the firewall & underneath but enough that a person would want to keep a eye on it. I ask him if there was anything I could do & he said he didn't have a single tool with him. I gave him some paper towels to wipe things off & told him to start it & see if he could see where it was coming from. He did & we couldn't see anything leaking. I gave him my business card & told him I was only two miles away & call me if he needed any tools & I would bring them to him. Well I never heard anything from him & had pretty well forgot about it until yesterday when I got a gift card from him from that local quick shop. He also wrote a note in a Thank You card & said it was a simple fix (his mistake a simple breather tube). I sure wasn't expecting anything. I was just trying to be helpful.
