I went to Nice N Clean today. I was in the 1st bay. At first, machine appeared not to be working after taking my $$...then it started working. I did the pre-soak & the foam brush. Then it shut off. No warning beep plus I should have had time left. I was left with my car covered in suds.....I tried calling the number listed on their wall with NO LUCK. It rang & rang...couldn't even leave a message. I won't be going back there.
