This sign was hanging in the deli section of a local grocery store:

Attn: Everyone
Every night the Chix wall
must be Full…and
covered with Plastic…no no
Questions Asked!!!

What does this mean?

Some hypotheses:

1. Cheese was misspelled.
2. It’s referring to the place with all the chicken.

Added to entry: My friend pointed out that chix is an abbreviation for chicken. I’m down with that. But then why does the chicken wall have to be full every night? Do people eat that much more chicken than other meats? Is cheese not as popular? What about plastic covering for the other items? And why is this such an inflammatory issue that someone needed to put up a sign about it?

So many questions.
