That sucks! But we participate in a very genteel sport and must maintain it's decorum, Serena Williams comes to mind as someone who sets a sterling example. Maybe if you would have keeled over from heat prostration and bled all over the court that would have been preferable, blood's really difficult to get off a court.
At my club, the owner won't put up a shade awning because it "would block the view of the spectators"--of what?-- players keeling over from heat prostration!
What is a real bummer are hoity-toity country clubs in Palm Springs, that won't let one play bare-foot on the grass courts. It is truly one of tennis's great sensual pleasures to run around without abandon, hitting tennis balls on a grass court, bare-foot. Your body and anything that may ail it are cured after a week of it.
A couple of clubs that allow one to play bare-foot on the grass are Baker City, Oregon and South Cowichan on Vancouver Island.
At my "home" club--more like a half-way house for tennis poseurs--the club "pro" made me put my tennies on; it was a beautiful hot day and another moment of abandon stifled by the kill-joy of proper tennis decorum while Rome burns.
Sorry, hope I didn't hi-jack your thread too badly, I've been playing in the sun too long today, at ye' old club.
Cheers and don't let the *******s get you down.
