US Open: Winner or Loser?

The US Open an example of some of the world's greatest athletes performing on the world stage.  At the hotel where I am currently, there are a number of tennis stars, juniors and administrators.

In the lift earlier this week I spoke to an individual in tennis gear who was wearing US Open identification.  I wasn't sure if she was a fan or player, but based on what she was eating I had to ask:

Darryl: "Have you been competing in the US Open?"

Girl: "Yes!"

Darryl: "Is that food [insert #1 fast food chain of your choice here] a part of your training regime?”

Girl: "Errmm, no."

Darryl: "Surely that can't help your performance?"

Girl: "Errrm, no."

Darryl: "So why are you eating it?"

Other: "She can eat what she likes as she burns off all those calories!"

Girl: with no hint of sarcasm, "I know it isn't good for me, but it is the only thing I could find."

Bear in mind, this is in midtown Manhattan - surrounded by lots of food choices: Including a 24 hour 'healthy' food bistro in the foyer and 24x7 room service availability.  

I am sure not the only reason why, but they didn't win the next day...
