I had a sign up in the Coffee area at our HQ's:

Your Momma went home on leave!

If you screw it up, CLEAN IT UP!

(Okay, the soldier talk has been edited out, but......)

The BC let me leave it up for a week or two, then made me take it down as some people were offended by the language.

At the PO, there's a sign up stating that the refrigerator will be cleaned out at 5PM on Fridays, and anything left in it will be thrown out.

The custodian was a little over zealous. About a month ago he went in and threw everything in the fridge out....................even the lunches that were in there for that day.
