What random act of kindness done to you do you remember?

My car broke down on a lonely dirt road 20 miles from the next town (a tiny place with a population of less than 100) , after several hours waiting a couple of tourists in a van stopped and after hearing my problem they drove on to the town and sent a mechanic out to me by which time it was night. The mechanic got my car going and I stayed at the town campsite that night , the tourists in the van were also there I thanked them of course and also paid their camping fees for the night.
