From a mostly negative review of Craigie on Main posted on OpenTable's user feedback area:
"There was also a black board at the back of the room where the wait staff kept score on certain orders which indicated to me that they were being bonused for pushing something."
This, of course, is the 86 board, in plain sight of all diners, which tells servers which menu items are running low or the kitchen is out of. (They also hated how the paper tablecloths curl up at the edges.)
Oy. This is one reason the industry hates amateur reviews.
