What annoys you about people using mobile phones when you're out with people or just in general?
I really can't stand it when your hear people in public toilets answer their phones.... just yuck. Also people in cinemas or at shows who don't put them on slient.
If out with friends etc I don't mind if they answer the odd text message or take a quick call. I do get pissed if they sit there checking facebook at all or spend an age on the phone just having a catch up chat. Phones have this great function now that means not only can you recieve calls but you also have the ability to CALL people when it suits you.
Does anyone have any others?
