The Management has also observed that although customers could have made it, they select not to wait if the waiting time exceeds their maximum allowable time for them (note, the cashier

notifies them that they need to wait over 75 min).

The aim of the Management is to reduce the number of dissatisfied customers and then to find

a way to improve the waiting time of customers. You may suggest any change you consider

feasible and important.
