Teenagers work in a barbecue shop. Is it safe to work at night?

Not safe. Teenagers are growing up. Working at night will lead to the disorder of biological clock and affect their healthy development. They should try not to work at night and bring home the bacon. Teenagers don't have the ability to deal with emergencies, especially barbecues are easy to meet drunk people. So it is not safe for teenagers to work in barbecue shops at night.
