A number of times I have received incorrect clarification from schedulers. Shops rejected, overturned and paid for.
This happened to me recently and it was not overturned but the wonderful scheduler gave me a similar shop to do and added the $$ I lost for the first shop to a bonus on the next one.
A high layout shop was rejected on a Friday night. The skeleton staff for the weekend insisted it could not be accepted. I chewed my nails down all weekend until the Monday staff reinstated pay and reimbursement.
I was once rejected on a shop I never even applied for. I did not discover it until 6 months later when I applied for my first shop through that msc. They told me I could never work for them due to the flaked shop I had 6 months before. No great loss as the owner had a real attitude. Other than that all my msc seem to be flexible with small issues.
The personal pizza shop where I was asked to re-verify the timing for putting assembling and baking the pizza. No one else was in line and the pizza was baked in record time. I was told there was no way pizza could have baked so fast. I went back and spoke with manager who confirmed my timings could have been correct. I was not blowing any cover because I will never return there even on my own dime. Pizza is overpriced and not so tasty.
My favorite was when I had a supermarket shop rejected because I did not evaluate one of the departments (seafood.) The instructions state that if you are at the counter for a specified time period (usually 2-4 minutes) and are not helped, you skip that section. Well, all the employees were clustered around a sample table (Boar's Head had some cheese cubes and deli meats on display) and they all ignored me when I asked if someone could help me in seafood. So I put this in the report, and I get rejected ( I did the rest of the shop perfectly.)
Wouldn't you think the client would want to know that the staff was so busy eating samples meant for customers that an actual shopper was being ignored? Think again, apparently.
