They don't send changes to you about your shop in an email. They don't post guideline changes on our shopper news site. They post the changes on the "CPI and guidelines." They want you as a shopper to read the guidelines and be "observant" to changes. That tells them a lot about you if you are or are "not" reading your guidelines. That is how they measure part of your shopping skills.
It is a loss to you what happened. But the client wants certain things done a certain way. The MSC won't be paid and neither will you. Think of it from the client's perspective. They did not get what they paid for...
You've heard this: If you don't perform it the way the client wants, you won't get paid. You saw the letter about shop times right? If you shop outside of 11:45 to 1:15 PM as example, (either earlier or later than) your shop will be rejected. (unless you can show their timing is off by so many minutes on the register).
Why are you shopping that client if the food is lousy? I happen to not like the greasy tacos you need to order for another client's location so I don't shop that assignment anymore. If you don't like the food, why are you wasting over $10 for it?
You mention not telling the truth (or considering it) but who have you helped by doing that?
They are not concerned as much this round with employee errors as much as they are with timing. Timing is everything! If you say your cheeseburger should be chicken nuggets, that delays the time in getting true times out for the orders. You keep the cheeseburger and report what happened.
You want to give the client what they want. They want timings. They don't care as much about the incorrect orders and there is a subsection for you to address any concerns about incorrect orders.
