3. You’re polite to everyone.
According to the rules of etiquette, you should be polite to everyone regardless of their age or position. If you want to get a waiter’s attention just nod, smile, or raise your hand. In big restaurants waiters usually tell you their name when they greet you. Try to remember it and use it throughout the dinner. “Would you please” and “Excuse me, Miss/Mister” are acceptable to use too.
2. You always go first if you’re a man.
If you need to get to your seats but a part of the row is already taken, don’t pass with your back toward the people in the seats. The same rule applies to similar situations at conferences, movies, theaters, and all other places with theater-style seating. Plus, if a couple is navigating this together, a man should go first and a woman should follow.
1. You hold your glass right.
During a cocktail party, you should follow certain rules as well. Use your left hand to hold your glass, so that your right hand is free for greetings and handshakes. Eat snacks that you don’t have to bite several times. And when drinking a glass of champagne, hold the glass near the rim, since only waiters hold it by the stem.
