(Article by Michael Holden) Near where I work the pattern of lunchtime activity has been affected by the arrival of a van a couple of weeks ago that sells Burritos. Everyone has gone nuts for this and the queue snakes halfway down the road. Ordinarily I would be reluctant to take part in such a phenomenon, but the food’s too good. I was in line the other day when a woman from further behind came up and started talking to the woman in front of me as though I wasn’t there. I held out my phone quite conspicuously between them and recorded what they were saying. They didn’t notice. They had better things to think about.
