Is the delivery man tired?

The delivery man's salary is lower than that of the waiter, but it's easier. Unlike waiters, deliverymen have to take care of the turnover in the store and look at the faces of the guests. The delivery man is different. Just finish the delivery. The waiter's salary is higher than that of the vegetable delivery man because they have a commission. There are waiters in the lobby who can learn a lot, but the delivery man can't. The last point is promotion. There are more opportunities than waiters.
