As we admitted, the waiter misheard and wrote down "boiled potato only". That was an honest mistake as we had absolutely nothing to gain from. When you received your ordered, you mentioned that you wanted the grilled veggies that supposed to be on the side, which arrived as soon as possible. It was only when the latter happened, that you said that you had ordered mashed potatoes, but then you changed your mind to fries. No wonder that the meat looked overcooked when everything was sorted out. We should mention that none of us got rude in any way, instead we tried to make it up to you. We even offered you chocolate and biscuits cakes. When the waiter asked you if everything was fine in the end, you responded "good". So it wasn't justified at all that you took the initiative to leave €23 less and leave silently.
