Yikes. The reviews on this place are awful but I tend to agree. I've been coming here for years and never been too impressed. I come here like many because it's convenient and most of the time they do a somewhat decent job. Saturday they were slammed, like ridiculously busy but I had driven from Queen Creek to get my car washed so we waited. The wait wasn't bad at all for as many cars/people that we saw.
In my opinion, they need to hire more people for the weekends. The workers there are in such a rush that they aren't even able to do a good job. I will say I don't see them standing around, I feel like they really are working hard and just aren't given enough time. If you come here, just know that when you get home you'll have to finish the job..
