Hello Feeshmon, welcome to Askgamblers forum.
Well, I guess newbies at gambling always have thousands of things to learn as they go on, and reading the rules is one of them - in fact, it is the MOST IMPORTANT thing to do first before playing at any casino, and you have just come to one of the stumbling blocks.
A rule is a rule...a breach is a breach...a limit is a limit...casinos would stick to that like a leech...simply because their business depends on that. If the max withdrawal is stated as $200, I'm afraid there is nothing else that anyone can do, or help to waive that limit. Only the casino management can waive it, if they want to, but don't count on it.
