paying it foward

I was out working on lawn sprinkler systems today ( fathers day) I roll into my local 7/11 store . Here is a dodge mini van with tents strapped on the roof 3 kids and the hood up . Ohio tags and I am in maryland . He was overheating and didnt have any tools . Well on the heater hose a plastic "Y" had failed . Auto parts stores closed . So I have been in similar situations before . I look in my service truck and find a Poly Tee for lawn sprinkler systems , pliers and a screw driver . In about 20 minutes he is back together . He goes to try and pay me , No Thanks Just have a Happy Fathers day and go enjoy the beach
