"I would suggest skipping the tip at this restaurant. Normally, I wouldn’t say this about any establishment, but the staff here come across as rather entitled, so I won't be contributing to that. Just a reminder, tipping is not mandatory. I'm looking forward to coming back and just paying for my drinks, as that's the only way I can express my dissatisfaction. Don’t worry, I’ve already returned without leaving a tip. I look forward to your closing day. Good luck trying to spot me; maybe you haven’t yet. See you on the floor? Haha, see you tonight."
