From what aspects can hotels provide better service by using the law of perception?

Give some examples to show how hotels can provide better services by using the perception rule:

As designers, we may think too much about fashion and beauty when designing hotels. As managers, we may think too much about how to generate income. But have we really considered the confusion and difficulties of front-line waiters in the service process?

Room attendants are mostly women, and they are weak. They often delay a lot of room opening time because they can't drag out the bedstead (cushion) of the room, and some waiters even resign. In the picture, the bed wheel installed under the bedstead of this guest room has a switch device, which is convenient for the waiter to pull out the bedstead to make the bed sanitary and will not move the bedstead when the guests check in. Achieve a win-win situation for guests and waiters.

From economy to mid-range business to high-end luxury hotels, it is believed that almost all bathrooms are equipped with "anti-skid pads", but not many of them are labeled "Please use anti-skid pads in the shower" because not every guest will use anti-skid pads. It is necessary to set up such a sign without hurting elegance, which can not only remind guests, but also avoid slipping accidents.
