Mystery shops don't always help. In fact, I'm not sure why management pays for them if they're not going to do anything about them.
I've shopped a quick fire pizza chain several times in my area. One of the stores, in particular, is absolutely horrible with a manager that doesn't seem concerned about anything. And he sets the pace for the whole crew.
Multiple times I've reported on the specific facts I've seen. I didn't submit opinions, only accurate facts. But, I've been brutal when describing the manager's actions and pace.
Every. Single. Time. I. Go. Back. He's still there and it's still awful.
Why do they pay for the reports?
On another note, as soon as Kroger discontinued their "old" surveys, they no longer seem to care if there are carts present at the entrance. I really wish they would bring the "old" survey back and stop asking me to count every employee in the store.
