I wouldn't normally write a review of a gas station/car wash, but I'm annoyed after leaving this self-serve wash with a car covered in water spots that will take days to get off. There was NO soap in the gun, even after spraying for two minutes straight. this left me to rinse the car without getting it clean, leaving the spots. Now I know why the bays were empty the entire time. Oh, and the vacuum was weaker than a Dustbuster.
