The only way to deal with Arny is just to say what you think and if he
doesn't like it not to worry too much about it. He has his opinions,
you have yours, and that's the deal.

In my area we have this one son of a bitch stereo store owner that is
always howling how he is an engineer. We have mostly figured out if you
just laugh at him everything works out better than if you try to debate
the issues.
