There are times I go through the car wash and there will be 2 attendants -one on each side working on car and I feel then the car is getting a good prewash before the machine kicks in but then there are other times there is one attendant and he only gets 1/2 of the car as a prewash-and I am thinking WHAT-isn't he going to come to other side-but at this point the automatic machine kicks in and off I go. It is just not consistent. If there is only going to be only one attendant then he should do the job of two and then turn the machine on, Keying in the code immedately as you enter does not give a single person enough time to prewash completely both sides of car.
