Interactive signage sells beer on the streets of Amsterdam

I wouldn't think you'd need any help with that, but apparently Grolsch beer and JCDecaux felt otherwise. Of course, the interactive signage in this case isn't of the electronic variety at all, it's just a clever mechanical setup. Take a look at the video:

Rumor has it the first take of this video featured a guy high on one of the city's many legal drugs, who opened and closed the door for a half hour before JCDecaux strongmen carried him away.

(yes, I'm kidding)
