"Excuse me, like you, I'm on a job that I don't really like or want to have to do, but also like you, I need the money, so help a brother/sister out. Please try not to stare at me awkwardly while I ask you a question I'm supposed to ask, and hint, your answer is going into a report, so try to fake liking your job, even though I know it sucks. You never know, maybe you'll get a Christmas bonus. *half smile* Who the hell are we kidding? You're not getting any bonus. *big toothy smile* Do you like working here?"
There is the truth.
Then there is the right thing to say.
