I think we all have little stories of trying to be nice and people take advantage of your kindness, behind our shop is an apartment complex, so one morning I see and hear this car coming up the street left side driver wheel flat, the guy is trying to drive to the nearby store to get air, well I have a long air hose on my tank so I yell out for him to pull over. I pump his tire up and send him on his way so I thought for the next week he was stopping by and asking for air, I had to stop being nice and told him this is the last time get your tire fixed.
