The joker has been adding ridiculous prohibition signs to the escalator for several weeks.
As a joke, the guy started putting a ridiculous prohibitory sticker on the escalator every day. The employees did not immediately notice that something was wrong.
The guy decided to add humor to the boring daily routine. For two weeks he established his hilarious prohibitions in a public place.
He put stickers on the escalator with such ridiculous restrictions as a ban on vacuum cleaners, monkeys and dinosaurs. After the thirteenth day, when the guy banned chickens, the staff removed all the stickers.
