Want to know the source of that problem? Look in the mirror.
If you want to let these folks control you in that manner
that's your business - but it sure isn't my style.

There is still a widespread perception that it is necessary
to raise one's voice when speaking on the phone. I can
remember being unable to make a call across Paris about
30 years ago. I also remember a Frenchman who would always
scream at the top of his lungs whenever speaking on the
phone or radio. However, I don't remember problems of that
sort here in the U.S. So I don't know where such ideas
come from.

Having said that, I see no reason why using a cell phone
is inappropriate in any situation where normal person to
person conversation is acceptable. Like in a restaurant,
on a bus or airplane, standing in line, etc. And what
difference does it make whether, in my office, I answer
the phone on my desk or the one on my belt? All that is
required is to keep the volume down - be it one's voice or
ring tones - and to be considerate of others present.
