I spotted this very innovative cigarette dispenser in the French department of Haut-Rhin:
Supposedly, you discard your cigarette butt according to which sports team you support. But if you stop and think a bit: do you drop your butt below the team you favor, to show your support – or do you drop your butt at the team you least favor, thereby giving them your butt (so to speak)?
When you stop to think about it, there is really a big assumption built in!
