1. Not leaving a tip for a waiter or waitress that relies on them. To pay their rent and buy their food, some of them need tips. If you don't, you may be the reason for someone's financial difficulty. It is selfish and rude.
2. Clicking your fingers at a waitress or waiter. It is annoying and rude
3. When a waitress gives you a meal or a drink or whatever, DON'T EVER say "Good Girl" People feel intimidated when you say this and it makes them feel small. It is also extremely rude.
4. Talking with your mouth full. It is disgusting so just, don't do it. We don't want to see inside your mouth at the mushed up food in there. Ewwwww!
5. Being to loud and raucous. People are there to enjoy a meal and you are ruining it for them by shouting and screaming at the top of your lungs. It always annoys me when I see a group of grown adults screaming and shouting.
6. Letting children come and go as they please from the table. Again, people are there to enjoy their evening. Little tiny 5 year olds disturbing everyone ruins it.
7. Holding your cutlery weirdly. It is not necessarily disruptive but it certainly is annoying.
8. Blowing on hot food too loudly. It's weird and sometimes unintentionally, you can spit at the other person.
9. Checking your phone at the table. It's rude because it's like you are blocking out the other person and don't want to talk to them. They may feel offended too.
10. Slurping your drink. Noisy. Weird. Rude. That's all I have to say.
