My first summer job was working in a Hallmark card factory. I thought it would be a lot more fun than it was. It certainly made me appreciate a chance to get an education. It was in a dusty wooden building with loud machinery, and a few of the experienced workers were less than friendly to the summer help because we tended to slow things down. They needed the bonuses that they could get for speedy production. I felt bad for them, but don't think they made things any better for themselves by making young people feel bad. I didn't see anyone who wasn't trying hard.
By the way, we were amazed while vacationing in Oregon a few years ago that they did not allow motorists to pump their own gas. Apparently it's against the law (or was at the time). Of course, they were not rushing around washing windows and checking tires and oil as they did when I was a kid, back when gas at the local Fina was 19 cents a gallon. (Does that ever make me feel old!)
