Fake power outlets at airports??

Encountered recently at an airport: I did the old find-a-power-plug dance, sat down next to this one, and only then noticed that it's fake. It's a sticker, a photo-realistic image of a power outlet, made all the more convincing by the scars and damage. Where did this come from? Who did this, and why? I laughed; I may have cried. Then I moved on. Maybe it was to make me feel human in an environment of cold practicality - or maybe some jerk just likes messing with people. Who knows?
