cellphones and interruptions

A huge problem with cell phones is that they make you interruptible nearly all the time. So many times I'm sitting in the cell culture hood pipetting, or injecting a mouse, and the phone rings. It's a major problem just to see who it is because I usually have both hands occupied. I know, you can turn off the phone, but who wants to bother with that? Only when I go into meetings do I silence it completely. Not even vibrate; how many buzzing cell phones I've heard at meetings...

But one place I will absolutely not answer the phone is in the bathroom. That is supposed to be a sanctuary, a place where no one can reach you. And it's just plain weird to talk with someone with your pants around your ankles.
