Well... not all the customers, just the retarded ones that can't read the sign saying the card machine isn't working.
Today at work, our card machine wasn't working so it was cash only. We put up signs saying so.
One at the front, middle and back of where the line queues in front of our register, as well as a LARGE sign in front of the register saying the same thing.
"Card Machine Broken.
But every 3/5 customer wants to pay with their card, and I'm the sorry son of a bitch who's got till duty all day.
I've never wanted to hurt customers so badly, not even during the Christmas rush.
