Rude service, twice now.

I love coming to this place especially because it’s close to my house but I’ve witnessed this now 3 times I’ve been there recently. I had a waiter who was very rude to a few of my friends that I was with, we asked questions nicely or jokingly and this man replies with the rudest response with the rudest attitude, he forgot my drink but I saw him write it down and I ordered first. When it was time to pay, we split the bill and left a tip that we felt was appropriate for his service ( after the rudeness we still left a tip) and he had the audacity to stop at the last person to pay and basically stop us from paying our bill because he DEMANDED that he get more, mind you we teens and young adults ( maybe that’s why he didn’t respect us ) but he would not let us pay our bill until he got a biggger tip and this isn’t the first time and it’s with a different person, it really spoils our mood, the waiters are ruining it for you. I feel like they need to have a discussion with the waiters because we really felt harassed and like we had no choice :(
