Customers may have started it but I suspect it will end badly. I'm pretty mild-mannered but one day, after spending ten minutes "putting my clothes back on" after clearing security, waiting for seemingly everybody else to board the plane, fighting for a centimeter of space in the overhead bin, and then squishing into my tiny seat ... somebody in front of me's going to lean back crushing my magazine into my chest and I'm going to snap. Tongue in cheek (kinda) but, seriously, this madness has to end and I suspect it will end in more legislation.
