Back when I was living with my grandma, we actually had a sales lady call and basically laughed at my grandma's last name.. and completely butchered it, then laughed again.

Getting it wrong is one thing, and pretty easily forgivable if you're nice about it.. but laughing?! woah.
I can't remember what my grandma did, but I know it wasn't nice =)

This story reminded me of that. It's insane how some of these CSRs act... and telemarketers... sheesh
