Alt text: a text post that reads:
Work in retail long enough, and you'll eventually realize the rules for dealing with Customers are exactly the same as dealing with the Fae:
Avoid eye contact.
Never reveal your full name.
Accept nothing They offer you.
Never verbally agree or disagree with anything They might happen to say.
To apologize is to acknowledge a debt owed.
Under no circumstances are you ever to thank Them.
Remember that They are incapable of reading signs in human languages.
Is that a US thing? Not here atleast.
It is a US thing, although exaggerated for comedy. At least when I was in retail, I did several of those things.
