Reminds me of Bothersome Man but shorter.
I was thinking The Truman Show.
This one is longer and is awesome because it's shot in actual ikea stores. more info on the piece
Is there a plot to that thing, or do they just continue being boring at each other? I gave up after a few minutes.
No real plot, more like a series of sight gags plus didactic pondering on the nature of private property and commerce. Some touches are more subtle, like the store PA changing language from english to german to hebrew because he shot it in multiple countries -- you can't tell from the style because Ikea's products hardly vary worldwide.
