Why doesn't the hotel elevator door show the floor?

I've been on a business trip recently, a little more. I noticed a detail. Many hotels have no floor display screen on the elevator door. Instead, there are two lights up and down to remind you whether the elevator is going up or down only when the elevator door is open.

At first, I thought it was just a hotel to save costs, because this elevator, without the display screen on the floor, can save at least tens of dollars. But it was later discovered that the higher the hotel, the more so. On the contrary, hotels at the lower end will show the current floor of the elevator.

This is very strange. When there is a floor display, we at least know how far the elevator is from us. Watching the numbers slowly approach our floor can ease our waiting. This is the countdown function. So why did the hotel do this? Are you more anxious to keep the guests waiting for the elevator?

There must be a reasonable explanation behind all seemingly abnormal phenomena. Sometimes, you can think of it yourself without consulting the elevator manufacturer or your mother.

Let's analyze it first. Who is this cancelled floor show for?

For the people waiting for the elevator, of course.

So what information was fed back?

Of course, it is the floor where the elevator is currently located.

Then canceling this display is equivalent to canceling such information feedback. If the hotel cancels such information feedback, people at the elevator door will not be able to see the floor where the elevator stops.

So, what kind of information can be obtained from the floor where the elevator stops?

Of course, it is the floor where the last wave of people taking the elevator will go and the floor where the next wave of people going downstairs will get on the elevator.

Well, we can get so much information through the display screen.

When the hotel blocks this information, the intention naturally appears: don't let the people waiting for the elevator know the floor information of the people getting on and off the elevator.

Then think about it. What's the difference between a high-end hotel and a low-end hotel?

Of course, most people who live in high-end hotels are people with status, while most people who live in low-end hotels are ordinary people.

So, now think about it, is the answer obvious?

In order to hide the floor where people with status live (which is also a kind of privacy), high-end hotels will deliberately cancel the floor display.

To put it simply, I'm afraid no one cares what floor I live on, but if a big star lives in a hotel, the paparazzi want to know what floor the star lives on and don't want to be found by the star. The best way is to hide where you can see the elevator display screen, wait for the star to enter the elevator, and then see which floor the elevator stays on. Even if others sometimes take the elevator together and stay on many floors, it is completely possible to infer the floor where the star lives through multiple data collisions.

I haven't heard this from Baidu since I wrote the article. I don't know if this is the reason. Do you want Baidu to try it? Am I right?
