Finding the answer to these questions can determine an operator's success.
Customers can be a fickle group and are difficult to figure out.
One customer may be perfectly happy waiting in a 10-car line while the next will leave the lot even if only two cars are waiting. Another customer wants a total detail for the price of an express and still another is satisfied with a car that the operator feels is an embarrassment to the carwash industry. Peak hours on prime days are the hardest times to maintain an acceptable customer wait time. One thing for certain is that if customers don't have to wait in line, they will be more willing to turn into the location and get their car washed. When I encounter a line at a carwash, I usually decide to stop by later or go somewhere else.
