Manner seems like belonging to the by-gone era. The modern four-letter word is "rude".
Many people still believe that they can multitask and achieve best outcome. The fact is they can't, and many researches have proved that it is a myth. People talk while their mouth is full, text while they walk, talk on mobile phone while they drive, and "sleep" while they work!
Concentrate, your life and health could be at stake. If you ever have an accident because of your foolish act, don't affect other people and ruin their lives!
