Stop in for a cup of coffee

I got hired at I think maybe 15 years old for pumping gas at a full service station. First thing manager asked me after I got hired was whether or not I smoked. In my mind I am thinking define smokes please? As I did not like cigarettes. Hah. Once it dawned on him I was contemplating my answer he bluntly asked do you carry a lighter. To which I answered no, I do not. He promptly handed me a bic out of his pocket and told me, anybody gives you Shi** pull the pump handle out and point it in their window and with bic in other hand, tell them to get off your lot. And never stand in between the pump island and the car as they can fling the car door open and knock you over, always stand on top of the island. I learned a lot from that old codger.
Who would think a guy would have to learn self defence as a pump jockey?
