After having a rough day, and a stream of rude customers, a barista at CUPS in Virginia USA had had enough and wrote a message on a whiteboard outside the shop, warning customers if they weren’t polite, they’d be penalised.

The sign said that if someone orders “one small coffee” it would cost $5. However if someone said, “Hello, I’d like one small coffee please,” it would cost just $1.75.

“Working in a coffee shop, you get a lot of people throughout the day who come in and not conscious of their actions and moods toward the barista,” said Billie Byrd another barista at the coffee shop.

The sign is merely a friendly scare tactic than anything else, although it appears to be working, with the café only having to charge $1.75 for a small coffee.
