It illustrates "Chekhov's bottle" very well:

"Remove everything that has no relevance to the story. If you say in the first chapter that there is a bottle of Perrier on the table, in the second or third chapter it absolutely must land on a hipster's head. If it's not going to be smashed, it shouldn't be sitting there."

And perhaps the moral of the play is yet another variant of Chekhov's gun, but this one would be "Chekhov's framework"!
