Step-by-step explanation:
A restaurant owner should not close the restaurant over the lunchtime. He should only do that if he is sure that he won't have any customer over lunchtime but since he has fewer of them, she should open it.
Also, it is giving him the ability to pay for some of the expenses which is also good for the restaurant.
- The only thing that he can do is to promote some of the new lunch opportunities that people can have and that can help him to increase the number of his customers during lunchtime. For example, he can promote lunch opportunities to those people who are coming for dinner time.
