I’ve never heard of this - do people actually do this - or is this like requesting to see an elevators maintenance log the is on file in the managers office (e.g. something you can theoretically do, but no one ever does)
Personally I would respect a customer who asks to see the tags once to see if the place is compliant. It’s like when a customer corrects someone who asks if the sushi-grade fish is “fresh” or “never frozen” (being frozen at extreme temperature is what makes it legally sushi-grade and the equipped ships are often at sea for months, so “fresh” is just a buzzword). It’s encouraging when consumers know the product.
