That sucks. That'd piss me off too, go get 'em tiger.
When my second child was born, I brought in a 100 ct desktop humi with a variety of sticks and left it out for folks to help themselves to a smoke or two. I also left out a bunch of chocolate cigars. Two days later everything including the humi itself disappeared. I wanted to crack some skulls.
It was a small company, only around 50 employees or so and everyone knew everyone. Guess you can't trust anyone these days.
