I had a very nice young man in a gas station (lets call him J,) but there was no gas, only the grocery. I felt cheated out of my $5 worth of gas, and I had to buy 50 cents worth of candy to get a receipt.
A few weeks later I met the former owner at his other station, same gas co. He told me J was a recent African immigrant, rather young, and had tried to please by selling cigarettes without asking for proof age, not realizing the consequences. I guess the customer was a mystery shopper. The owner had lost his cigarette license and the station went broke and had to be closed. He said cigarettes account for most of his income. I felt sorry for J, having caused so much heartache. The former owner manged to give J another job, so all was not lost. I was glad I hadn't been the shopper. Was also surprised to see gas stations make most of their profit from cigarettes.
