B, because I hate revolving doors.
I hate them because I’m always afraid the other people in the door will turn it too fast, and I’ll stumble in them (though it’s never happened to me.) Also, it’s really awkward when you get stuck in a portion of the door with someone else (happened to me once.)
I usually use the revolving door. The ones at MIT actually have signs asking you to use them, since they help keep the heat on on cold days, and prevent wind blowing into the building at other times*. Sometimes, if I’m in a hurry, or someone else has already opened the ordinary door, I’ll use that one.
But revolving doors are more fun than regular doors (if harder to push). why not use them?
There is a widespread story in MIT legend that they had to put revolving doors in at the base of the Cecil and Ida Green Building/Earth and Planetary Sciences Building/Building 54, because the wind whipping from the the Charles River Basin (which is like a natural wind tunnel) and funneled between the Hatden Library and Walker Memorial was so strong that people could pull the ordinary doors open. So they installed revolving doors, which didn’t have that problem. They also installed Alexander Calder’s enormous Stabile scuplture The Great Sail, which acted as a windbreak. The story was repeated (with illustration) in Jearl D. Walker’s* book The Flying Circus of Physics, so it’s likely a rare piece of campus legend that’s actually true.
** No relation to the guy the Memorial is named after. As far as I know. Walker Memorial appears to have been the Student Center before they built the present Student Center. It has a dining hall, used cto have a snack bar, and Student Activity offices.
I never use a revolving door. They (scare me / give me the creeps / induce anxiety / make me nervous)–something like that.
Well, unless I’m carrying something which won’t fit there. Less heat exchange, they’re fun and while I’ve seen people try to stand in the middle of the way in a revolving door it’s never lasted long. Nowadays, automatic ones don’t need to be pushed, don’t give a shit if you push and stop if anybody manages to stay in the way for too long.
I used to work in a building where outside temperatures would be upwards of 36C/100F by about 9am for several months a year. There were so many complaints from the people manning the entrance desk about idiots using the little door and propping it open that it eventually was connected to their desk so it could only be opened by them, so long as the electricity was on (if it was “dead” it went back to being a regular handle/pushbar emergency door).
Yes, I too hate it when the person behind me pushes the door faster than I do. I’m always afraid that my heels are going to get clipped.
I like them. They’re like roundabouts for pedestrians. If there’s no one else around, I’ll go around a couple times for no particular reasons, just like I do with a roundabout.
Most places in Montreal have two sets of doors with a little airlock between them, to prevent an open door from blasting the lobby with winter air. With everyone here saying they take revolving doors to prevent freezing people inside, I’m suddenly wondering if maybe other cold-weather cities don’t have that setup? Why not?
I don’t like revolving doors. I always feel like I’m going to catch my purse or my coat in the mechanism somehow.
Sure, we have those too. In the building where I work, that’s the case with the middle entrance. The left entrance has a powered revolving door. The right entrance had a revolving door, but the ne temporary entrance is just a plain double door. The security guards hate it.
Do revolving doors in the UK go counterclockwise?
There is a revolving door at the main entrance the building where I work, but I always use the regular door beside it because it is very slow.
Regular door, unless there are clear reasons not to in a particular circumstance. If I’m somewhere where there are revolving doors, I’m probably on an errand or on some other mission, in which case I’m in “efficiency mode” (no nonsense, fast walking, … my days are too packed to amble when doing chores). I can get through a regular door without breaking stride, whereas revolving doors are usually like swimming through molasses.
It’s not that I actively analyze the doors’ relative efficiencies or anything. It’s a subconscious thing, like if there were, say, a police-tape barricade you needed to cross and you could duck under it or step over it. You wouldn’t sit and ponder which is the easier way. You’d just naturally do whatever was easier without really thinking about it. Same with doors – I just subconsciously take the easiest route.
No, but I think they do in the Southern Hemisphere.
I avoid revolving doors if I can. I remember the climatic scene at the end of The Godfather.
There’s a Blue Cross building here with those two sets of doors, and you also have the option of a revolving door. I take the regular doors.
Near Bonaventure metro, though, while walking towards Place Bonaventure, the only option* is to use the revolving doors. As I’m often there at rush hour, and there are large crowds of people going through the revolving doors, I really hate it.
*They have regular doors too, but those are usually locked.
(Maybe hatred of revolving doors is a Montreal thing? 
)
They often do, but if the entrance is busy enough, or even just if the airlock is small enough, both normal doors will be open at the same time.
Always the revolving door, unless I’m carrying pulling something too big to fit. If it’s a cold, windy day, I don’t see saving 3-5 seconds of my time as being worth being a dick to everyone else in the lobby, even if I am in a hurry.
Besides, they’re fun!

Whee.
As mentioned in our previous communique.

Yep especially at an office building. From 8:35 to 9:15 it is usually a constant stream of people and both doors would be open freezing the looby.
I thought it was kind of weird here in Detroit. A disgruntled dude drove his cat through the front doors of the Ren center. The first thing I found amazing was that they just let it sit plywooded over for about three months. In a city that has huge image problems, and a building that is that the showpiece for both the City and GM they just let it sit with the front door boarded over like an out of business pawnshop. I don’t know if it was an insurance dispute or what, but spend the 15K and fix your damn door.
The second thing that amazed me was that when it was replaced they just skipped the revolving doors and airlock and put in a single panel of swinging doors. In Detroit, In a building situated at the end of downtown off the river that will magnify a 10 Mph ENE wind into a 60 MPH gale. That lasted till the first week of November, when they again boarded it up and came out three weeks later with revolving doors again.
But they put in shitty three chamber doors. I freakin’ hate those, because the end up with a panel sitting directly in the middle of the opening most of the time. So you either have to squeeze into the chamber with a laptop bag and other bags. Or you have to break stride, stop and get it started turning by pushing it right from the outside which breaks all rhythm.
Or, to quote a thread I started a while back:
Dalek voice: “Whee! Whee! Whee!” 
Now I am picturing Daleks going through a revolving door. Has this ever happened in an episode?
I can’t remember the last time I saw a building with both revolving and push-to-open doors where the push doors weren’t locked.
It must suck for the handicapped who need them, because I imagine they have to sit outside flailing to get the front desk guard’s attention to be let in, and it gets cold in Chicago in the winter.
Another vote for using them for fun! If no one’s watching, I might even go around it a few times fast just for the hell of it. Sadly, buildings with revolving doors are often very busy 
I’m one of those who has never seen a revolving door in real life. Every place I’ve ever been deals with the draft problem using a two door solution with a small area between them. I have been to a city big enough to have revolving doors, but I guess I never went to an establishment that used them.
It’s one of those things I’ve always wanted to do, but seeing as I only see them in old TV shows, I’d assumed they’d fallen out of fashion.
