i dont agree with that at all, either that, or i am working with a very unusual bunch of people.
the people i work alongside are all brilliant communicators - thats the majority of this job - talking to people. i dont think you can do this job unless you can talk to folk, without winding them up.
i really dont see my colleagues swear at people, if i did i would say i agree with you, but seriously, unless i have joined the most unusual force in the uk, i just dont see it!
and really sometimes, people try the patience of saints, like the man who belted his 78 yr old mother black and blue, then smashed the house up before he then drove pissed to his gfs house where he hid in the shed until officers got there, and where he then hurled hammers at them...he was told to get on the "effing" floor but only after he tried to take a few officers out first.
its easy to judge in these situations unless you are on the receiving end. i have personally never sworn at a soul, but i wouldnt rule it out if someone was taking pot shots at me with a hammer....
