My DC has been working in a bar/restaurant that is part of a chain. The bar closes at 10 and that is when his shift ends. However, the staff often hang around after closing hours for a few drinks. They don't pay for the drinks. My son says the manager encourages this. Is it normal? I'm concerned he will get into trouble for it. Sometimes these "lock ins" last into the early hours so they must be consuming a significant amount of stock.
