Last week the New York Times' blog "You're the Boss" posted the second part of 100 Things Restaurant Staff Should Never Do by Bruce Buschel.
The second part of the list also includes some very key service issues, so I think this list has been a great idea. The comments are funny too, some people think this guy (who wrote the list) is a real jerk others totally commiserate with items from the list...
Here are some of the ones I liked from part 2.
#52. Know your menu inside and out.
#62. Do not fill the water glass every two minutes, or after each sip.
#64. Specials, spoken and printed, should always have prices.
#74. Let the guests know the restaurant is out of something before the guests read the menu and order the missing dish.
#77. Do not disappear.
