I noticed on several recent hotel stays a curious observation...especially for leisure guests...

As you are are moving up or down a high-rise hotel elevator, at each stop along the way, the door slides open and the people waiting to get on freeze and stare at the open car before reluctantly getting in.

The car is not full, and the few people on it already do not have knives and bloody clothes.

So what is it? Are they unsure of their decision to go up versus down? Have they never seen inside an elevator (maybe they've always used stairs in the past)?

Has anyone else ever noticed this?
