Those island counters that house the condiments and sauces. Know what I'm talking about? This is the only restaurant I can think of where guests can (and in some cases, must) walk right by the uncovered sauces to get to their table. It's bad enough that it's not stored back in the kitchen where only a few (hopefully) clean employees have access to it, but it's right there smack in the middle of the front lobby of the restaurant, uncovered for all the hundreds of people eating there every 24 hours to pass their germs on.
