Final answer:
Mickey Mouse observed that the lines at the ice cream stands in the Magic Kingdom are extremely long and proposed giving workers Powerbars to improve service speed.
Step-by-step explanation:
Mickey Mouse's initial observation was that the lines at the ice cream stands in the Magic Kingdom are extremely long. This is inferred from his proposal to give workers a Powerbar to speed up their ability to create ice cream cones, aiming to reduce the length of the lines. In real-life scenarios, similar efficiency problems can be resolved by analyzing the situation and implementing targeted actions, such as the lunch-hour manager's use of floor markings to direct customers in a busy restaurant, which resulted in an improvement in service and customer satisfaction.
