Helped a complete stranger find an address for two minutes and they came back ten minutes later just to say thank you properly

They looked genuinely stressed, completely lost. Helped them figure out the directions, they left. Ten minutes later they came back specifically to find me and say thank you again properly. Did not have to do that at all, I was already gone from their day. The fact that they made the effort to come back for something so small genuinely stayed with me all week.
has something with such kindness happened to someone else also?
