staffing is the main issue facing hungry's.currently,there are six servers at the order/pay station and two at the pickup food station throughout the 4-hour period. since they know that the bus arrives sometime during the middle two hours, they'er considering a variable staffing plan that, for the first and last hour would have three at order/pay and one at pickup food (note that the total number of person-hours on the payroll is the same, 32,under either the current staffing plan or the alternate plan, so the payroll cost is the same). what's your advice?
