I pulled up to the doors and waited 10 min.outside . A customer was allowed in at the door beside me so I waited. When I did get in there were people waiting to be attended to and getting frustrated for waiting. The gentleman that was let in before me had not been attended to and was wandering from podium to podium interrupting and being rude to customers because he felt he was owed service first. There was no control of this customer unfortunately. When I was attended to I had to go to a service desk that was at the other end of the shop.Just a little confusing that there was not enough manpower first thing in the morning when the appt. was made a 2 weeks ahead.
