Elevators for Dummies

Why is it that people have to jam onto an elevator like the next one isn't comeing for 2 hours?

I am constantly amazed at the people who will risk life and limb to catch an elevator. This usually takes place in an office tower where there are a bank of elevators whose sole purpose is to elevate worker bees to their cubicle. Another one will come, I promise.

Are you really in that big of a hurry to get to work that you can't wait 18 seconds for the next elevator?
