Bad tasting, shitty complementary coffee such as that set out all day for customers at a bank. It often tastes burnt if sitting in a pot or tastes weak or acidic if served from a thermos dispenser. Occasionally somebody will help themselves to a cup, but nobody really enjoys it. Often served in small white styrofoam cups with a large canister of powdered creamer nearby.
“Is there a place to get coffee here?”
“Nah, all they serve here is shitty bank coffee.”
Shitty, complimentary coffee that is watery or burnt but customers drink it anyway because it is free. The coffee is usually accompanied by a stack of small styrofoam cups, various packets of sweateners, and a large dispenser of powdered creamer.
"Blech, that bank coffee tasted like warm water but I had to stand in line so I just drank it anyway."
