Karla Gomez is the supervisor at the Grand Hotel's casual restaurant. Karla's 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 entrées or were just beginning their desserts. What can Karla do to solve the problem?
