Customers seeking this service arrive at the shop on the average of 2 per hour, following a Poisson distribution. They are served on a first- in, first-out basis and come from a very large (almost infinite) population of possible buyers. Golden Muffler Shop's owner is interested in cost factors. He estimates that the cost of customer waiting time, in terms of customer dissatisfaction and lost goodwill, is $15 per hour spent waiting in line. Jones, the mechanic, is paid $11 per hour. Compute the average daily customer waiting time, then the daily salary for Jones, and finally the total expected cost for 8 working hours per day
