What is the meaning of the protagonist's conclusion to Mikhail Zoshchenko's story "A Trap?" Why does the story end this way?

In "The Trap," by Mikhail Zoshchenko, a Russian visiting Germany encounters what he thinks is excruciating cleanliness. He remarks that even public toilets are sparkling clean. He thinks that he should take this cleanliness back to Russia, and tell the Russians that they all have to clean up their act.

However, he gets "trapped" in one of these public restrooms, and starts banging on the door to get out. It turns out that he has forgotten to flush, and the door will not open until he flushes the toilet.

In the end, he decides that maybe the cleanliness he has seen in this country is an extortion of the people. Germany must force its citizens, in little ways like locking the door until the toilet is flushed, to keep their own country clean. Although thus disillusioned, he still wishes Russia would think this way and therefore be as clean.

Essentially, the story's meaning is that if outer beauty has a price, maybe that price should be paid. Perhaps it is worth it!
