[zoombini]

But if your holding your breath, how do you tell the others to get out?

I can imagine the scene..
Zoombini gets mail, opens a package & discovers that its full of white powder.

Zoombini Stands up moves away from desk & then tells everyone else in the room to leave immediately because he has received a suspect package.

Zoombini leaves the room, informs management & gets told not to mess around, its probably a sample of dry powder fire extinguisher powder.

Meanwhile, other members of the department have sniffed & tasted it to see what it is.

But then thats the problem, people don't take things like this seriously..

I'm just glad that all our mail is opened down at the front offices.
(yes I know that they shouldn't, but they do & this is 1 of the only good things about it)

Asking management what the procedure is on receiving this would equally get dismissed.
