Since you haven't posted the name of the client, you can post the name of the MSC.
I did one parking garage shop for Ann Michaels (I think).I have blocked it out of my memory. However, the reasons it was so horrid were unrelated to the MSC or the report. The shop itself sounded simple enough. Park my car. Observe certain things. Interact with the attendant (ask for directions, etc.) and maybe a couple of other things.
BUT. Everything went wrong. 1.There was no address on the building and when my GPS told me to turn right, I turned into the wrong garage. It was extremely tight and someone had to help me back up and turn around. extra time. 2 I found the correct garage and had to drive up a very narrow lane with cars speeding by in the opposite direction;I almost got hit a couple of times. I almost banged into a couple of cars trying to avoid posts and obstacles. 3. I could not find a number of things I needed for the report. Extra time. 4. When I took a picture of the receipt, my camera was on video. I had to get my son to help me take a screen shot so I could submit it. EXTRA TIME. By the time I got home I was a mess. I will never do one of these shops again. Too much aggrevation for little money.
However, in a different locale it might have been the world's easiest shop. Garages in my town are a piece of cake to park in. So....
