Car wash mix up!

I have been using the BP station in Ashford Common (Middlesex) for many years now, usually with no problems. Until today that is! I clearly asked the cashier for a Gold Car Wash at a cost of £6.00. The cashier said something like "a jet wash then". I corrected him and asked for a Gold Car Wash and he charged me £6.00. I then went through and put the code he had given me into the machine and proceeded with the Car Wash. I noticed that the dryer did not turn on and subsequently my car was not dried. I went back into the shop and spoke to another cashier about this. He checked the code I was given on their system and came back saying that I asked for a Jet Wash as stated on my till receipt. I tried to explain that his colleague did not listen or at least understand what I had asked for in the first place, that I was not happy with the level of service I received and the fact his colleague got my order wrong. He did offer me another Car Wash Code (which I would have probably been charged for again) and almost didn't let me have my receipts back. He also showed me their Car Wash price list and guess what, my car should have been dried, I pointed this out, but he insisted that I originally ordered a jet wash. Feeling aggravated, I took my receipts and said that I will not be visiting this station again. He tried to call me back, but I had no choice but to walk out. Therefore some of the staff do not care if they get it wrong, are rude, try to take over when you make a purchase, don't listen to customers and can't seem to tell the difference between a car wash and a jet wash. I definitely will not be comming here again!
