The increasing use of mobile phones on trains and in restaurants shows a serious lack of consideration for other people. Yes, of course, it is very convenient to be able to conduct your business while travelling or waiting for your food, and, whether we like it or not, the technology is here to stay. But nobody really wants to listen to one end of someone else's boring conversations throughout a meal or a journey. The same phone user would soon object if I were to read aloud from the newspaper and disrupt his or her call. Therefore, given that people should treat others in the way they expect to be treated themselves, mobile phones should not be freely used on trains and in restaurants.
