I guess it would depend on what your responsibilities were working at the restaurant, for me since I was the oldest I had to replace the oil in the fryers and do maintenance on them (dissembling the front console and looking for shorts), as well as training and evaluating crew members on the various stations we had. I was put on the night shift where I would have to close the store at 2 am and wouldn't actually leave until around 3 or so (cause of the cleaning), and since I was the only one with a car I would have to drop everyone off THEN try to get enough sleep to go to my second job in the morning (6 am). I was responsible for counting and recording ALL the cash drawers as well as the store's safe, if something didn't add up it's an automatic suspension. I've dealt with customers just like OP on a daily basis, making side remarks on where I was and what I was doing, but when in fact there was so much more to the job that goes overlooked. All this and I was still getting only 8 dollars an hour. As I was working in fast food, I had a college education, three years working in behavioral health and substitute teaching... and the only reason I couldn't get a job was because there wasn't any available- (a large number of departments were reducing staff). So yeah, there was a reason.
