I Think people are very rude and about 95 percent of people either cannot read or don't care. In Doctor's, Dentist's and Hospital waiting rooms people are asked to switch off their Mobile Phones, but do they,? of course not. It really annoys me when I see someone using their mobile for either playing games on or just having loud conversations by someone who has called them or they just make their own calls or loud musical texts coming in as well. was there life before mobile phones I wonder.
