Continuous Poor service

How many reports should one log before ANY improvements in service will be seen?? Especially when certain managers are on duty. Getting service from the kitchen is a joke you wait forever, on the bingo side it's even worse! Link tickets on Saturday was sold still after 9 pm yet the links start on the hour. Can somebody PLEASE sort out your POOR service or is this a standard practice??? Phone calls and empty promises from senior management is just not good enough
