A few more rules to add to the ones below…
Only do this once per store, or if you continue to, make sure it is always a different employee.
Make sure there is no place the employees can place, or hold your food where you can’t see it, if not…
Be ready to eat phlegm, or hamburgers tenderized by the old shoe and floor process.
