I personally don't like say you are in queue and someone is on the phone they don't even say to the person on the phone hold on while I am in a queue and whilst they are being served ignore the server and carry on talking. I find that kinda rude.
Good answer . I try not to do it hardly anyone rings me on my mobile so IF it goes I know it is importantish. I always ALWAYS apologise to whoever I am physically with no matter who thay are friend or random.
One thing that WINDS me up beyond belief is not making eye contact with who you are speaking to . That is to me shear ingrance and RED RAG to a bull .Also a weak handshake I do have to be careful with that cos I do have a decent grip no GRAB IT LIKE YOU MEAN IT MAN !!!!!.
My dad always said manners maketh the man he was so right the older I'm getting the more I relise he WAS right. Never would have told him that while he was with us I'd have never have lived it down him being right
