I agree, it's just that it didn't sound right to me in that dialogue as an answer to the given question. Try it. Ask the question and then say "you bet!" See, it doesn't sound right.

"rather!."................ old-fashioned and middle -class enthusiastic agreement.
I thought about that, too, that it sounds a bit old-fashioned. Maybe a little "toffee nosed". I guess I read too much P.G. Wodehouse.
It's just such a good translation of "еще бы", I couldn't say no.

pick a nit sounds pretty hilarious because we say someone is nit picking as an adjective but it is very funny when used as a verb here, but it doesn't seem out of place in the context of a comedy.
I liked it, too, and it fits the meaning of the Russian well. More the sense of being "officious" rather than careful.
