Relations on the tables would likely get you shut down, but you'll probably just get blank stares and a lot of "Ohnodayditant!" if your off-the-clock relationship-building exercises cause you to spill someone else's $9 drinks at some clubs.
The Newsreaders act like there are "surprises" when they list the restaurant sanitation ratings, like when a country club or a fancy restaurant gets a B, but it's usually in the upper B's, and they regrade it to an A. And then you gotta think, at any given moment, sometimes restaurants are short-staffed, so that costs them points, but sometimes they are just sloppy and take shortcuts, and that costs them points. People usually can tell, over time, which places habitually groom themselves at the register, leave their refrigerators open, and store their raw meats over their flour bins and dead birds in the freezer.
