Okay, so I've done the shop, and I'm sorry for not being more specific, but I really don't want to out myself to the MSC on this forum. I do think they are on here.
So, on to the problem: The MSC did respond to my email, but did not really give me a scenario to follow, and told me to ask general questions (directions/hours/etc).
I read the questionnaire thoroughly. Now, here is where it gets tricky: the shop is in a sports related industry, a sport I know very little about. I looked at the questionnaire and it had a couple of questions that seemed specific to a scenario, but since I had no scenario, I asked a friend who is better acquainted with the sport what I should ask. I did not want to give myself away as a shopper. I think I got through the phone portion okay.
The other thing that confused me was that one of the questions on the questionnaire implied that I was to purchase some time doing said sport, except the assignment did not pay enough to cover the purchase of sports time. It paid enough to cover two other purchases, and the MSC's email only said to make two smaller purchases. So, that is what I did, and explained in the narrative that I was instructed to make the two other purchases, not the sports purchase. (hope that is okay)
Another thing I noticed in the questionnaire, is that it looked like the client wanted me to interact with as many employees as possible and rate their customer service. Hooray! I can totally do this. Except, no one at this assignment had a name tag. I listened for names, got a couple, and just used descriptions for the rest of the staff.
Anyway, that was just one shop of a few I did today. It was definitely a simple one, or a complicated one, depending on which way I want to view the thing. I'll wait to see if I get approved.
