If I had Carla waiting for me in an air conditioned hotel room, I might be tempted to default a match as well.
Coria seemed kind of like a prima donna to me. His game was okay...on clay. One of the funniest matches I ever saw was him against Agassi at the Aussie Open. Agassi seriously ran him back and forth for about 2 hours, and by the 3rd set, Coria just gave up. Defaulted the match and went back to the wonderful AC of his hotel room.
