trash

When we first moved into our building there were very very few residents who had moved in yet.  Most were still fixing up their places.  Occasionally there would be construction trash left in the elevator.  Annoying, but not really a big problem. Mostly just an occasional box or packaging material or something like that.  Now that more neighbors have moved in, in the past few weeks a terrible habit developed.  People were just throwing their bags of leaking, nasty trash in the elevator.  Seriously.  for about a week everyday the back half of the elevator had either bags of trash or leftover gross-ness after the cleaning ladies had to clean it up.
In my head, I was drafting a sign that I could print out and hang up.  I was wondering what words I could use that would express my disdain for the situation and not be too blatantly rude.  I hadn't yet completed my masterpiece when I noticed someone beat me to it....and did a much better job than I could have:

"Take out the trash.  Maintain civility."  

That's my rough translation.  Anyway, it seems to have worked.  Since the sign was posted the elevator has been trash free :)
