It does happen! I used to fly a great deal around Europe (less so now) I was always diligent about switiching off my phone before boarding. (for one thing it gave me a couple of hours peace). Then one day of course I forgot. We were on the taxi out of the apron at Clermont Ferrand, when my secretary called me. I closed the call immediately but judging by the reactions of my fellow passengers, I had contracted some highy infectious disease and was about to spread the germs throughout the cabin. They had never done anything wrong - ever, of course. I am not sure the crew even noticed, they certainly didn't say anything. Somewhat remarkably, I was allowed to fly with Air Littoral again.
