He did say, Fook yoo, in a very French way though, including an expansive gesture, class.
I always remember being in a French taxi, I kinda loosely knew the couple who ran the firm, divorced from each other but still having to work together and it was her who was driving the taxi. Her phone lit up and his name was clearly displayed. She pressed her bluetooth headset and answered the call with a long withering, Oui, drawn out with so much expression in it, that I felt the need to sink slightly in the seat and look out the window.
I practised saying it by myself for days after but I couldn't get one tenth of the expression she had managed in such a short syllable.
