During the Cultural Revolution customers have to treat shop staff with respect and submission: the workers are the bosses. Now kindness and politeness from the staff towards customers are encouraged again.
This poster actually was first published in 1965. It soon became obsolete - or even counterrevolutionary. Apparently the design was judged strong enough to be reprinted after so many years, and to get a new chance under new political circumstances.
