Don’t sit first
One of the most important rules that you have to take into consideration when going to a fancy restaurant is not to sit first if you are the guest. You can ask the host to suggest where to sit.
“When arriving at the table, avoid sitting down first if you are the guest,” says Geiger. “Instead, allow the host to make recommendations about where to sit.”
If it is a work-related meeting and you are the host, then important managers or VIP clients should sit on the spot with the best view. If it’s a party, then make sure that people who don’t get along don’t sit next to each other so as not to spoil the atmosphere.

Don’t raise your voice at a server if you want something
This rule should be implemented in every restaurant out there! You should never ever raise your voice at a waiter or waitress to get his or her attention. If you need something, then use eye contact or your index finger. “You should use eye contact or put up your index finger of your right hand, ever so slightly,” says Napier-Fitzpatrick.
“The person hosting the meal is the one responsible for getting the attention of the waiter so that they can order,” she says. “If his clients or anyone he’s entertaining isn’t happy with their food, he’s responsible for getting the waiter to come over and change it.”
So, whether we are talking about fancy or basic restaurants, you should never yell across the room to get your server’s attention.
