Repair Shop Wait Times. What was the longest wait?

It is at a Bergys Truck Repair. They have a large facility with about 20 bays. It just bothers me that such a big place can be so slow and unresponsive. They are the biggest around and seem to be unconcerned about my business. As it stands, they've removed one of my calipers a month or two ago, so I couldn't drive it elsewhere even if I wanted to. Maybe a mobile mechanic could save the day.
