Replaced window motor & annual inspection

My parents have used Bill for repairs, oil changes, and inspections on their old GMC cars since he opened his shop in their neighborhood many years ago, and I've been using his shop for the past few years. He has always been knowledgeable, honest, reasonably priced, and prompt. He's earned our trust. Today my 90 year old mother needed a fix on her 13 year old Buick - rear side window had dropped out of whatever holds it up. We arrived at Bill's shop late morning on a Saturday - and the place was BUSY with cars lined up. We could see that he didn't have time for us. I asked a young mechanic about the time and cost to do a halfway "fix" - put the window in a permanently up position. (The age and condition of the car doesn't warrant much of an investment.) He gave us what I thought was a fair price considering that the door had to be opened up - under $100. Could it be done today? As a favor to a long and loyal customer, Bill agreed to squeeze us in. I deposited my mother at Cindy's Deli & Pancake House across the street, and returned with the car to Bill's shop. As I handed Bill the key he quietly recommended (didn't push) a proper fix on the car he has been servicing for more than a decade. I asked about timing - he'd need parts and it was a busy Saturday. He asked me to give him 2 hours. If he couldn't get and replace the window motor within 2 hours, he'd do the half-way fix that I first suggested. (We both knew Mom didn't have enough stamina for much more than 2 hours.) I agreed, and walked over to Cindy's to wait with Mom for Bill's call. After exactly two hours the shop called ~ the car was ready. As I was walking towards the shop, Bill was pointing at the inspection sticker. It had expired and we hadn't noticed. He offered to do the inspection - it took only minutes. Like all the other times we've taken our cars to Bill . . . we have no complaints, nothing but praise. I don't know if I've ever seen Bill smile ~ he's a very soft-spoken, rese
