An etiquette guide for servers: Redux

The New York Times blog You’re The Boss is back with the second half of its “100 things a restaurant staffer should never do.” And although author Bruce Buschel suggests that these are merely guidelines for his restaurant, the insinuation is that there’s a lesson every server can learn.
It’s interesting to watch Buschel’s tone change slightly from what he describes as “a modest list of do’s and don’ts” in part one (published earlier this week) to the end of the second post’s introduction where he thanks the Internet for its helpful comments. Not to get too meta, but there’s an etiquette lesson somewhere in this etiquette guide.
