I tried these shops earlier and have some comments after reading these.
There are a bunch of Popeye's in my area. I originally planned alot of these for a day. I think they want independent eyes on the inspection so nothing looks like a conflict of interest. Closed-toed shoes are mandatory for kitchen entry simply for food safety - regardless of who walks back there.
As for the work itself, I noticed many of these franchise managers don't read their emails from corporate or tell their shift supervisors that these audits are coming. I came to one site and halfway through my audit, I was asked to leave until the actual restaurant owner was there as they weren't aware of this audit (the supervisor was apologetic). I would even call ahead and ask the manager to let them know I'd be coming and one thought I was a telemarketer while others refused to let me come there.
This becomes an issue for both the contractor and the marketing group because while these are somewhat surprise arrivals, the restaurants are told ahead of time that we'd be arriving some day so I'm sure the marketer is caught in the middle of expecting corporate to have done their due dilligence. I had surprise audits for gas stations like the Shell and Philips 66 ones and I'd get a "oh yeah, I heard you'd be coming" or the sticker audits with "yeah, I remember seeing that email." With the Popeyes, proceed with caution.
