Well I agree with Sbrintz, There is many a time someone has bounced off me whilst focusing on their phone, looked back as if to say wtf, then scurried away when they see what just happened.
But despite the Bose Ear Warmers making the world a better place, I still seem to have the sort of appearance that makes random people want to talk to me even with them on.
Why just today, whilst stoically staring at the fondleslab with the ear warmers on, waiting for the tram, I was asked what my opinion was of the new shelter and the quality of the woodwork on the benches.
As for escalators and the Iphoneistas, an accidently placed shopping bag in the back of the knee works wonders.
