Before long every cashier is going to request a smile from you, scripted as the most friendly way to say “please let me shov this scanner on your face”
The psychological effect of being requested to smile every time you make a purchase will reinforce your behavior to purchase more and appear less miserable keeping up the illusion that everything is cool and normal.
I am just talking from my ass but gotta remember that the ceos species have their asshole below their nose.
