This is indeed an all-too-real sign my super put up in my building in New York. Or should I say, "all-too-real"?
Just so you really completely understand what we're dealing with here, let me type this out in crystal clear ASCII:
"ATTenTsion"
ONLy - RuBBiSH-To-Be-PuT-iN
THe- "BuiLDiNG-Shoot-!!
"Do-NoT-ThROW-ANY"-
Re-cycLe-DOWN iN THe-SHooT-
Put-ALL-Re-cycle-iN THe-"BasemenT"-
"THank-You"
-"ManagemenT"-
I think it's the unclosed quote before "building" that I relish most...
