what? Average waiting time would equal the amount of time a customer waited. You'd have to pick a certain amount to be constant-- such as how many customers' wait time you are counting. By collecting the data, how would you find out their wait time? i.e., they take a ticket when they get there with the time stamped on it, and when there number s called, wait time end. after that, you add it all up and divide by the number of customers who's wait time was included.
