What slogans should be posted on the walls of the case handling area?

The slogan about caring for the walls is not that rigid language. It's like that kind of personification or metaphorical slogan, like don't touch me, I'm afraid of getting dirty. Or an interesting slogan, just love the wall.

Slogans about protecting walls in personification and metaphor types:

(1) I am afraid of touching, please don’t touch me casually. I'm more afraid of getting dirty. Don't put dirty things on my body.

(2) Do you want my body to be filled with psoriasis-like advertisements? Please don't paste random advertisements on my body.

(3) Please don’t destroy me, I am everyone’s protection wall.
