There is a crew of guys with brushes and hoses. I have been there and there were 4-6 guys in there, and one day there was only 2. The manager told me it was supposed to rain that day so they didn't expect much business. I think it's well worth it for the cost. They will spray your truck of also even if you elect not to have them wash it. At least at the location I go to.
