The Community Y is a multi-purpose gym where members can swim, lift weights, run, play court games. Milo has worked the front desk check-in for almost 30 years claims that the Y has a membership over 10,000. This is about 1/3 of Muscatine, Iowa. As you can imagine, checking into the Y results in bottlenecks and wait times that adds to the cost of membership. I often hear members complaining that more personnel are needed at check-in to speed things up. I'm not sure.
When people populate the Y, they check-in, workout, shower/change, and check-out. There's only one exit/entrance point. Let's assume that the workout and shower/change are independent variables that don't effect the time it takes to enter or exit the building. This problem reminds me of debits and credits in accounting. The two have to equal. So it makes sense that the people coming in have to equal the people coming out.
What bothers me is that there's always a bottleneck checking in even when the Y doubles the personnel that checks in members. Why?
