The cafe is almost empty. A customer tries in vain to choose a meal to his liking. The barmaid and two waitresses are discussing a recent radio program in which a retired waiter talks about the plight of his colleagues in the old days. The customer is nervous: borscht is impossible to eat, crayfish is already peckless, milk is sour, beer is warm.... The disappointed customer, leaving, says that he was the one who spoke on the radio. The waitresses apologize: they thought it was an ordinary customer, but now they will serve him in no time. The man refuses and in a peculiar way - by verse and personal example - gives a lesson in cultural service.
