A CAFE owner is sick of coffee addicts forgetting their manners when ordering a cafe latte or cappuccino.

Marisel Valencia Madrid, 41, has become so incensed that she has imposed a ‘rude tax’ on her coffees, reported The Times UK.

If you don’t say please or thank you in your order, then the coffee will cost a whopping $7.35.

If you are polite and order a coffee at beachside Restaurant Blau Grifeu in Llançà on the Spanish Costa Brava, by saying ‘buenos días. Un café, por favor (hello, one coffee please)’ it will cost €1.30 ($1.90).

Slightly less courteous, and if you only say please, that same coffee will cost €3 ($4.40).

Now if you are downright rude and demand your coffee, without a please or thank you, then add another €2 to your coffee, bringing the price to a whopping $7.35.

The charges are explained in a poster outside the restaurant.

“People seem to be in a rush these days and forgetting to say ‘please’ when they ask for something,” Marisa told The Times.

”I put a sign in the window with the price system and it has made all the difference. People are now super polite in all matters and it has really improved daily life.”

The idea was inspired by a bar in Paris, France, that offers discounts depending on the politeness of its clientele, according to Verne.
