Is OTHER wrong in the post ? POST : Okay, the title makes me sounds really NTA, but there's more to it. Actually, it's a wall of text. But I felt like it was necessary to show my thoughts about the situation.


I go to this relatively upscale restaurant with my friend, who I'm paying for, I'm not very wealthy but I decided to splurge a bit for once.

Until I'm supposed to pay, we had a very good experience, the food is fast, very tasty, the waiter is quick, friendly, refills our drinks and even asks if we want her to get a bag so we could take the leftovers home... I was actually so impressed that I was going to give her a relatively big tip. (tipping in my country is not necessary, it's something you give if you are really happy with the service)
 and this makes me feel a bit bad for getting pissed off at her.

Anyways we had a coupon that gave us 2 desserts for the price of 1 so we ordered desserts. I order a slice of cake and my friend a small ice cream. No problem here either. But then when we are done I noticed the bill was unusually high (I had made a price estimate in my head, and this was much higher than that) and I ask to see the receipt before I paid and I noticed I had been charged for both desserts. I point this out to the waitress and she said the small ice cream was excluded from that coupon, and for it to be valid we'd have to buy a big ice cream. I ask her to show me where it said that it was excluded, well, she has nothing to prove that. The coupon had a small text that stated desserts with alcohol was excluded from that deal, but nothing about small ice creams. 

Then she just standed there for some 30 seconds thinking or something, and told me we could compromise. She said she could be ''nice'' (said without sarcasm) and reduce our dessert bill from 11,90€ to 8,90€, but if we had the 2 for 1 deal as advertised it would cost us 7,10€. I told her this and that I was not going to pay a cent more than that, because I felt like I had been scammed. Then she answered ''you will just pay 1 euro and 10 cents more than you'd have to do with said deal'' in an annoyed voice. I replied, ''I'm bad at math, but even I know that it is actually 1,80 euro, but I don't want to pay extra for something I was never informed about'' .

Not because I can't afford the small difference, but I wanted to stand my ground against what I felt was bullshit. We had some back and forth, but I was never rude to her (except speaking in an annoyed voice towards the end) or called her names. Finally she agreed to let me pay the original 2 for 1 price and even brought me a calculator to show me that 89-71 is 18(???).

When I was there I felt like I was right the whole time, but on my way home I started to doubt, because before the scene she seemed genuinely friendly with good service.
