The Excessive use of mobile phones
In addition to the use of Social Media by those that I think should really know better, the over-use of mobile phones is also a bugbear of mine.
I don't think that I am alone in this observation, in fact there are many accounts from those that also are also appalled by those that insist on having their mobile phone on the table at a meal or in a resturant.
In addition there are also reports of mental health issues with this behaviour. ADDT
