I have done a ton of gas station audits.
Just did two for a different brand.
Part of the shop involves checking if the cashier has a name tag.......
If the cashier doesn't have a name tag you are supposed to take a picture of the person without a nametag!
(1) I am extremely uncomfortable taking someones picture without their permission.
(2) In both cases I asked permission and was denied.
I felt really dirty for even asking.
