Revolving Doors

The revolving door is an amazing invention. Think about it: what's better than a door that's never really open?

Apparently, the first revolving door was invented in Germany in 1881 by a man named Bockhacker - ten years after the unification of Germany (Question: could Germany's unification have played a part in the development of the revolving door? No! Not even a little bit, dumb-ass!). Bockhacker ended up calling his invention "Tür ohne Luftzug" or "Door without draft of air" (Wikipedia), a very descriptive name. Legend has it that Bockacker was originally going to call his revolving door "The Uber-Sexy Entry Experience" but was talked out of it by both his mother Chlodwig and his aunt Engelbertha.

Anyhow, there should be more revolving doors. Obviously, they are energy efficient - they can save both heat and cold air. Drawbacks? It's difficult to get a large amount of people quickly through revolving doors (Look up the fire at the Cocoanut Grove in Boston for proof). I've tried many times, and the results have been disastrous - including several fatalities. I have usually done pretty well when using revolving doors. I walk proudly through them, knowing I have saved energy by avoiding those lame doors that still use handles. Sometimes, though, I have entered a revolving door only to find that someone has come up behind me and walked into the same revolving door section. This, obviously, is extremely frustrating. When two people are in the same section of a normally sized revolving door it becomes rather difficult to move. I have always wondered what would possess an individual to assert themselves like that and encroach on another individual's revolving door personal space. I'm sure others have had the same thing happen to them, or can at least imagine what it would be like to have two people in the same revolving door section. It is terrible. The person who used the revolving door properly is unfairly punished by the transgressor behind them. They step on the back of your feet and sometimes rub up against you. An injustice followed by more injustices.
