Mom and Dad taught us some basic etiquette rules to follow at the table: keep your mouth closed while chewing, don't talk with your mouth full and keep your elbows off the table. Although that last one may no longer be very important, the others still are, especially when it comes to what not to do at a business lunch. In addition, there are other rules to follow. They may seem to be simply a matter of common sense but given what the author has seen of late, that commodity seems to be in short supply.從小我們就被教導：進食的時候應該把嘴巴合起來，當嘴里都是食物的時候不能說話，手肘不要放在桌子上。盡管最后一條聽起來沒那么重要，但其他的還是很重要的，特別是與別人共進工作午餐的時候，除此之外，還有一些規則要遵守。也許看起來如同常識一般簡單，但就筆者最近的觀察，這些注意事項都被大多數人忽視了。

　　1. Don't Floss Your Teeth1. 別剔牙。

　　While there's no arguing the importance of dental hygiene, tending to it should never be done in public.沒錯，保持牙齒清潔衛生是很重要的，但是這決不能在公共場合做。

　　2. Don't Brush or Comb Your Hair2. 不要梳頭發。

　　Nobody wants hair in their food and when you run a comb or brush through yours.沒有人希望在你梳理頭發的時候發現有一兩根在自己的食物里面。

　　3. Don't Blow Your Nose3. 不要擤鼻涕。

　　While we're on the topic, if you sneeze at the table, go to the restroom to wash your hands.當大家正在談話的時候，如果你打噴嚏，那么就請移步洗手間并洗手吧。

　　4. Don't Talk on the Phone4. 別打電話。

　　If you get a call, go elsewhere to take it, but only if it's a good time to do so. If you and your dining companions are in the middle of discussing something important, wait for the best opportunity to leave the table.如果你的電話響了，請到別的地方去接聽，但當然要在適合的時機才能去。如果你正與合作伙伴談論重要的事情的時候，請等到合適的時候才去接聽電話。
