And their supervisor has this unusual speech pattern where everything he says sounds like he's pissed. Imagine "I LOVE YOU!" (menacing angry voice) "YOU DID A GREAT JOB!" (menacing angry voice) "WHAT DO YOU WANT FOR LUNCH?" (menacing angry voice). So you can never really tell when he's angry or not - it's like he was taught to speak English by people who were chronically pissed off, and he only has one inflection.
I swear, I've worked with this person.
