Concerned gas station attendant?

I just paid for gas inside a 7-11. I tried to pump the gas but it didn’t work. I went in and told the cashier the pump didn’t seem to be working. He said I took too long to get to the pump and he gave me a long explanation about their pumps and a new system and more. He said he adjusted the pump and I should try to pump gas again. I said I’ll hurry out to the pump. He said “don’t run in such a way you will hurt yourself” I laughed! I also ran out to the pump in an awkward and to me amusing way.
