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.
Working in tech and retail showed me this. I decided to make it up to the world in general, in a small way.
So now, every christmas, I find some of the services I use (like my bank, full of VERY helpful, friendly people) who have call centres active on Christmas day, and I ring them and say thanks and Merry Christmas.
The only downside is occasionally someone will cry because a random stranger wished them a Merry Christmas because they're at work.
That's awesome. We had a customer who would call in about once a week just to say hi and thank us.
It's not supposed to work this way - but I guarantee she got the best service of any of our customers.
I once had a customer call me back after a bad call, and apologize for being rude. It did nearly make me cry.
