Annoying Doorbell

We have this annoying doorbell chime at work that detects when anyone comes through the door. Like a department store, except we are not a department store. Supposedly, this little device will help the boys know in the back when someone comes through the door for help. I find it rather annoying-- we have tried multiple things. A web cam underneath a computer monitor to track people when they come through the door and the guys keep a window open on their computers to see the traffic... we have also had those bells that you tap to "Ring for Assistance", however people would ring those stupid bells when I am sitting right here at this chair. All they have to do is say, excuse me ma'am, " I need help with -------" but NOooooo. They just wanted to ring the bell.
So now we have this door chime hidden underneath the desk overhang pointed at a weird angle so that if you plug it in, it chimes four times. For some weird reason I think that if I run through the door fast enough, it won't catch me. Stupid thinking, it always does, and I always groan when it dings and they all laugh at me in the back. We need a taser system or something so when someone comes in all they say is OW! And we know they are there. Okay-- maybe not that violent. haha
