As someone who worked tech support for four years... this.

That's why I always try to be as entertaining as possible (while still being clear and helping them solve my problem). I recently had to exchange a pair of pants that I really liked but didn't fit on an online store. I ended up describing receiving their pants "As if the mighty Norse god Thor himself rode down from Aesir with a lightning bolt in one hand and these pants in the other."

I figure their lives are hard enough, might as well make them smile sometimes.
