Pasta with duck €8.99 + €8.99 ‎ = €17.98 Accidentally paid with two twenty euro notes, so €40 I should get change = €22.02. What did I get? 5€ change for 40€, they simply kept the 20€ which was too much and didn't want to give it back, the change wasn't right either at 5€. The gentlemen can neither speak German nor do math, which is very, very annoying.
