I just subjected myself to the horror of shopping. These days, everybody seems to be in town and in my way. At the entrance of the one mall-thingy they have one of those large revolving doors. Now everybody knows that revolving doors aren't very efficient in terms of letting many people through in little time, and they aren't terribly fun to use unless you are a little kid, superman or into pushing pensioners around.
With those large, electrically driven, revolving doors that seem to be so popular these days, it's even worse. First of all you have to go through it at the space the door wants. That is, unless the door stops because it thinks it's about to crush someone who accidentally touched a bit of it. While this stopping thing may be important for liability reasons it is plain annoying and it can - well, does lead to deadlocks. This seems to be mainly because using these doors is more complex than the traditional one-person-per-compartment doors, the concept of which is reasonably easy to grasp. Thus people always try to squeeze into an already filled compartment of the door, annoying everyone this way and probably being slower themselves compared to having waited for the next compartment coming round.
I guess the main point is that both the door and the people are too stupid for their own good - and for mine. I'm all for sliding doors:
The irony circuits cut into his voice modulator as he
mimicked the style of the sales brochure. “All the doors in this
spaceship have a cheerful and sunny disposition. It is their
pleasure to open for you, and their satisfaction to close again
with the knowledge of a job well done.” (The Hitchhiker's Guide to the Galaxy)
