Free vacuums nice but, can get very busy at times. They get a lot of traffic that leads to packing in cars one after one; which at times, makes me feel we are too close together in the wash and the car behind me may run into mine when I am slowly going through the dryer. With this traffic comes equipment maintenance issues that occur and slow things down even further.
By the way, sometimes I feel I don't get the premium wash that I should because the run both lanes, the auto and the pay as you go, I don't think the wash knows what car is which.
Some issues here for sure, but what can you expect...it's a car wash.
