Keep having to come back for follow-up work. Last time got some tires and had to bring the car back to get balanced; and hour wasted. This is basic stuff that should have been done when the tires were put on.
Update: An hour and twenty minutes later I went up to the front to ask the associate if the car was ready, and his reply, "well we haven't gotten your Car in yet." This is from the same person who told me, " we'll have you in and out within the hour."
Just tell your customer that you are running behind; that's not that hard, so they can make changes to their plans.
Go to the Sears Auto near Fiesta Mall; excellent customer service.
