When your customer service drives this kind of hammer wielding behavior from the proverbial "little old lady who drives to church on Sundays", then you're doing something wrong:

"I scared the tar out of some people, at least," she says. "It had never occurred to me to take a hammer to a phone company before, but I was just so upset. . . . After I hit the keyboard, I turned to this blonde who had been there the previous Friday, the one who told me to wait for the manager, and I said, ' Now do I have your attention?' "

Somewhat extreme, but I have to say, I've been tempted when the phone rep tells me "we don't support Linux", or "we don't support Mac" - when the problem is that the cable modem has no signal.
