Queueing

This one is for Tom and David:

Everyday at lunch, I get frustrated. I stand in a well organized M/M/3 or 4 queue and within moments it deteriorates into multiple M/M/1 queues and inevitably I end up at the back of the longest. I stand there and can only throw my hands up as a wave of people push past me on every side in the firm belief that they'll be better off - and this from a culture that prides itself on efficiency.

While I doubt Americans have the upper hand in this, and are capable to puzzle together the right way to queue, I am thankful for the operational engineers who slap up some good old fashion barriers and force people to stand in line the most efficient way possible.
