Clean Freak has a solid car wash, free vacuums and friendly service. The quick detailing they do for less than $20 is ok, but you can just use the vacuum yourself and save the detail cost and tip.
The one time I did have them clean the interior then my car didn't start afterwards (I later determined I needed a new battery - stupid AZ). The manager was super nice and was ok with my car being there as I figured it out. Another extremely nice customer left and got his battery charger and despite his help it wouldn't start. I eventually got it out of there, but the staff was very friendly, concerned and helpful when they didn't necessarily have to. Kudos to the staff!
