These are the dangers of going to an interview totally unprepared.

French tennis player Nicolas Mahut was probably in a bad enough mood already after his first round loss to Mikhail Kukushkin in the French Open, but things were about to get a whole lot worse.

The opening question in English at the press conference after the match came from a journalist who had not watched it, and was told that Mahut had won, so he started with a friendly "congratulations". That didn't go down too well.

Fail to prepare, prepare to fail
