Why do big hotels often have revolving doors?

I’m sure you’re familiar with revolving doors. These types of doors that work like a turnstile are often found at the entrance of department stores and large hotels. Consisting of several wings, usually glazed, the user pushes a wing, causing the entire door to turn. By walking with the turning wings, the user then exits the dial on the other side. Interestingly, the direction of rotation doors is usually counter-clockwise.  See acast.com/privacy for privacy and opt-out information. Hosted on Acast. See acast.com/privacy for more information.
