Don’t take those crappy mystery shopping assignments that don’t offer any pay, only reimbursement. Except maybe the one to a steakhouse – reimbursement to eat there might be worth it. Your time and effort writing those stupid reports are worth more.
I’ve been dabbling in mystery shopping for years. I’ve enjoyed some great shops, even got some with good pay. But on the whole, it’s not worth it. The pay isn’t enough for gas, for my time jumping through hoops and writing about it, for the hassle of getting this circus out of the house and herding them there like recalcitrant cats.
