Have Some Integrity
I work at a grocery store. One day an elderly man was cashing out his groceries, in the middle of the process he proceeded to have a minor heart attack and faint to the ground (it could have been something else but he grabbed his chest).
As the paramedics were putting him on the stretcher, he started to get up and insist on paying for his groceries. Most dedicated customer. Story credit: Reddit / Fatliner
