Barry Milnes (Not sure how it is spelled) a real pain according to him Andy is the only one in the whole world who swears on a tennis court.
Andy has been fined for swearing but so has a certain Mr Federer too
Not the worst though, I think Ferrer has been fined the most for that. I'll have to find the article
Novak Djokovic: 4,500 US dollars (500 for racket abuse at 2007 Wimbledon, 500 for ball abuse at 2010 Wimbledon, 500 for racket abuse at 2010 US Open, 1500 for coaching at 2011 Australian Open, 1500 for racket abuse at 2011 Wimbledon).
Rafael Nadal: 2,000 US dollars (coaching at the 2010 Wimbledon Championships).
Roger Federer: 1,500 US dollars (audible obscenity at the 2009 US Open)
Andy Murray: 1,800 US dollars (audible obscenity at the 2007 US Open, and racket abuse at the 2011 French Open).
David Ferrer: 9,250 US dollars (5,250 for audible obscenities, and 8 counts of racket abuse at 500 dollars a go, so 4,000 for that).
There's an interesting top 10 on there of the worst offenders - based on fines from the last 6 years.http://www.thetennisspace.com/top-10/revealed-officially-the-worst-offenders-in-mens-tennis/
