Karla Gomez is the supervisor at the Grand Hotel's casual restaurant. Karles responsibilities include overseeing five servers and two bussers, seating guests, and taking reservations. One Friday evening, the restaurant was very busy-all twenty tables were occupied, there was a substantial wait list, and there were people on standby. The service bar was almost full of guests, and most of the seated guests in the dining area had finished their entrees or were just beginning their desserts. They were not leaving, however, in part because of cold, rainy weather outside. The guests did not seem to be in a rush to leave the restaurant, but several of the guests waiting for tables were complaining about the long wait.
What can Karla do to solve the problem?
