You know how irritating mobile phone users are when they fail to exercise discretion and think the world needs to know their business? When you have enjoyed as much as you can stand, you can now get you own back!!!
After a busy day a man settled down in his train from Waterloo for a nap as far as his destination at Winchester , when the chap siting near him hauled out his mobile and started up:-
"Hi darling it's Peter, I'm on the train - yes, I know it's the 6.30 not the 4.30 but I had a long meeting - no, not with that floozie from the typing pool, with the boss... no darling you're the only one in my life - yes, I'm sure, cross my heart" etc.., etc.
This was still going on at Wimbledon, when the young woman opposite, driven beyond endurance, yelled at the top of her voice, "Hey, Peter, turn that bloody phone off and come back to bed!!"
