These folk do a great job. I typically get a generic wash and keep it moving. They are efficient in taking your ride through the process.
One tip watch the lip entering the store to pay for your wash. I have and I've witnessed plenty people not paying attention to this lip and tripping into the store. If you're in sandal s you'll burst that big toe right open.
Los turn that damn lip into a mini ramp; improvise, I'm withholding the final star until you do.
