Love these.

A couple of the secretaries are FURIOUS that when big-wigs from corporate come over here to use our conference room, they use OUR staplers and OUR printer (when the running costs come out of OUR budget) without asking permission!

A sternly worded notice has been blu-tacked to the conference room door. It is in ALL CAPS and has been laminated.

(I don't think we have a laminator here, so someone's gone to a fair bit of effort there.)
