For service businesses, Waiting Lines calculation and design can be a critical part of capacity. We encounter waiting lines on a daily basis. For this discussion board, please offer a personal experience of a waiting line that was either really good or really bad. In your discussion, try to analyze what they were doing well or changes that the business could make for improving your customer experience. Please use some of the terminology from Supplement B on Waiting lines in your description of the waiting line arrangement. (Phases, Channels, arrival rates, etc.)
