These people are the rudest men I have ever come across in my life! I can't believe they are still in business. My car was dirty and full of dog hair which we discussed on the phone, I said I would be happy to pay extra, but since I didn't have a ride could you do my car first. We were joking and laughed and then he suggested I not buy the Groupon just pay them the same price so they make more money, whatever. I got there and he saw the car got mad said I would pay extra, I said "I know it was discussed" and would I go first since I am waiting, his answer was "why should I, you have a coupon" NICE! He said he could guarantee I would be last and it would take about 8 hours. Good thing I hadn't bought the coupon! I suggest no one else do the same, they only want to clean, clean cars!! His partner was just as rude to me and made me tear up on the way home, is that necessary when you are in the business of customer service?
