Multi-millionaires throw in the towel

Novak Djokovic is the first man to earn $100 million in tennis prize money, but those staggering riches have not cured his habit of spiriting away coveted Wimbledon towels.

And the world's best player is not the only one happily stashing away the towels, which can be bought from the All England Club shop for $35 apiece.

"I try to sneak in an extra towel here and there during the match, using the excuse that it's too warm and I'm sweating," said Djokovic, who won Wimbledon in 2011, 2014 and 2015.
