Not sure where you are but no one has ever done that to me. I usually would go through self checkouts so someone just comes over, takes a quick look at my drivers licence, and puts in their employee id into the machine to authorise it.

I'm in the midwest, but at several large chains with hundreds of locations, even at the self-checkout when you buy booze, it flashes the little 'attendant needed' sign, the person comes over, scans their badge, takes your ID to do a 1 second look, and then scans it on the same barcode reader you use for your box of cereal.
