1. The hotel Manbhaavan provides room service (Food and Beverage) for its guests. The process for the room service consists of a room service manager who takes orders by phone in an average of 2 minutes per order. The manager then sends the order to the kitchen where it takes an average of 16 minutes to prepare the foods for each order. There are four cooks in the kitchen. If the customer requires a beverage (alcoholic or non-alcoholic), the room service manager sends the order to the bar at the same time the order is sent to the kitchen.
