Why oh why would you sit on the train and then, when your mobile rings, get up from your seat and walk up and down the carriage talking to your colleague "Martyn" about goodness knows what...
Maybe it's because everyone needs to have the benefit of your conversation. Oh no. We don't.
This man angered me.. I honestly thought he was going to sit in the vestibule area and take his call but instead he walked up and down like a caged lion.
Have you noticed people doing this - I have seen a few - the ones who have a compulsive need to pace up and down when talking on the phone - I've also seen security guards doing it 'cos they think it makes them look important.
Stop it. Sit down. Shut up... or talk quietly. The technology in phones these days really is very good and it makes no difference if you shout or not.
