No fury here, though some mirth.
Unfortunately mobiles are now just a part of most people's life (even, almost, their anatomy).
Asking them to be switched off? Nah, the point of this thread is
telling them....
While i will agree 100% about the annoyance of an apparent inability of some people to exist for even a few minutes without their life's inanities being imposed aurally on everyone around them... That discussion is completely different from the one that started this thread, viz "we're all going to die because 12A STILL HAS HIS MOBILE SWITCHED ON...AAAARRRGGGHH"
I humbly suggest TS that you merge this with the "obese" thread if you wish to introduce the "intruding on others' space/sensibilities!" angle!!
What would those posters do if one of their "larger" co-pax was also chatting on the phone...
