What are some suggestions for training staff to handle unusual circumstances?
Michelle Wong is manager of the Java Coffee House at a busy location on Union Street in San Francisco. Wong says that there are several challenges in operating a busy coffeehouse, such as training staff to handle unusual circumstances. For example, one guest consumed a cup of coffee and ate two-thirds of a piece of cake and then said he didn’t like the cake. Another problem is suppliers who quote good prices to get her business and then, two weeks later, raise the price of some of the items. Wong says that the young employees she has at the Java Coffee House are her greatest challenge of all. According to her, there are four kinds of employees—lazy; good, but not responsible; those who steal; and great ones who are no trouble.
