Auto repair service near Waterford, WI

I was in there on 05/06/2011 and I went inside to pay, Im standing in line there's an older lady that was at the counter with short brownish hair and a little heafty, then there was a customer that was not in line scratching off a ticket, I was the next inline after 2 ladies and the lady with the ticket jumped infront of me to turn her ticket in, the attendant working (the heafty one) say's to me "she was in line 1st" I said well It didnt look like it to me and I put my $ on the counter and said "I'm on pump #6and I have a crying baby in the car and I started to walk out. The attendant said to the customer with the ticket "what a rude trashy girl" I just kept my mouth shut and left, well the attendant say's over the intercom "I have your license plate # and dont come back." 1st off I did nothing wrong and she seems like the rude one calling someone trashy that she doesn't even know. How do you get business with having rude people work for you
