I am sure there are a dozen of books in the field of emotional stress which cover the effects of curbing ones feelings. Waiters, receptionists, air hostess etc. often have to put on a plastic smile in spite of how big a jackass they think the other person is.
On the other hand I have met a lot of people, esp. those who engaged suppliers, labor, contractors etc. who on a regular basis, yell and show anger on a regular basis. Its not that these guys are short tempered or like to show their position of power by abusing their subordinates, they yell because it’s their way of communication how important the task is. Some of them might be deriving some sadistic pleasures out of this, but most say that it’s the way of doing business. The interesting thing is that I have met so many of my friends who were swearing on top of their voice, making me concerned that there is a chance of a homicide here and the very next second they are back to normal. Being polite is a desired virtue which everyone should follow, but one cannot deny the fact that rising tempers often help to expedite the jobs.
Most books on emotional stress emphasize on the need to find a channel to vent out their frustrations. I am wondering if it is tiring for people who get more opportunities than they need to vent out their feelings. How they cope up and manage the pressures.
