大家说的都对，也许是Polite Discrimination的一个表现。
跟同事一起用餐要注意最基本的餐桌礼仪：
- 口里有食物时不要说话，吞了再说话。(don't talk with your mouth full)
- 嚼食物时要关闭嘴 （chew with your mouth closed）
- 不要大声打嗝
Keep these basic behaviors in mind as you eat:
1. Chew with your mouth closed.
2. Avoid slurping, smacking, and blowing your nose.
3. Don’t use your utensils like a shovel or as if you’ve just stabbed the
food you’re about to eat.
4. Don’t pick your teeth at the table.
5. Remember to use your napkin at all times.
6. Wait until you’re done chewing to sip or swallow a drink. (The exception
is if you’re choking.)
7. Cut only one piece of food at a time.
8. Avoid slouching and don’t place your elbows on the table while eating (
though it is okay to prop your elbows on the table while conversing between
courses.)
9. Instead of reaching across the table for something, ask for it to be
passed to you.
10. Always say ‘excuse me’ whenever you leave the table.
