Also a big fan of

if you see a price list/menu/price tag or similar and you accidentally read it, better double check the price by asking “does this item cost what it says here”

Because it happens when management has three different prices and five confusing "discount" offers scattered in line of sight. Is this 50% off or does that happen at the register or does it no longer apply? And you've got the same thing on the menu as a side and a meal, which one am I ordering, again?

And

“employees only” actually means “for adventurous customers”

Oh, bathroom for employees only? At every location inside three city blocks? I guess I should just take a crap on the floor.
