What's in an exclamation point?

People tend to abuse the use of the exclamation point. I don't know if it's like that where you work, but it's certainly the case where I do. Take this message in the mail room for example:

Do not touch the zip machine!!!
Contact Sue or Lucy to operate it!!!
This office is open from 8am-5pm M-F!!!

That's three sentences, nine exclamation points, in case you were keeping track. I think that's about 7 exclamation points too many. To me, using it would signify excitement, whether it's in anger or happiness. There's nothing to be happy or angry about when finding out you're not supposed to use the zip machine. (I also just found out what it is today. It "prints" stamps on envelopes, as opposed to you going to a stamp vending machine and getting actual stamps.) Also, did anyone else notice that the third sentence is totally unrelated from the other two? Did they just put it there to save the trouble of printing out a whole new paper with that single sentence on it?

And then there's the issue of mass emails. Something like "Printer 406 (by conference room 101) is out of order" or "Do not use the internet for non-client related purposes" both apply to me. But something like "Matt, please put the finishing touches on document 100009" needs to be seriously re-thought before it's sent out to everyone in the same department (incidentally, there are about three Matt's here) or anyone even remotely associated with it.

You really do see all kinds at the workplace. From finger-quotes guy (you know the type, they have to put every fifth word they say in quotes using their fingers while talking to you) to the when-I-put-something-in-italics-I-really-mean-what-I-say ("The meeting will start at 8am, promptly") lady, the office does provide some subtle entertainment.
