Final answer:
The statement about the six-minute standard for serving a custard treat is false; serving times are typically quicker to accommodate customer arrival rates and ensure efficient service.
Step-by-step explanation:
The statement that the time standard for serving a custard treat to a Guest is six minutes is FALSE. If one customer arrives every two minutes, then it would only take six minutes for three customers to arrive. However, the time to serve a custard treat is generally expected to be much quicker, so that the service is efficient and can cater to all arriving customers. The actual standard for serving time would likely be based on factors such as the complexity of the treat preparation, the efficiency of the staff, and the equipment used.
