Maybe because the guy with the erection is in Las Vegas when he wants to get laid, instead of being in Montreal. Most guys do not travel to a specific location just to get laid, but they want to get laid in each location that they travel to. Each market has its own pricing and structure. Montreal has its charms but it is not the only location in the world, although it is the best place in North America for mongering.
People go to Vegas to spend money, it's that simple. It is a magnet for escorts and they are crawling all over the place even though in Vegas, it is technically illegal but tolerated within the casinos at designated locations.
I have a friend who is thought of by many as the supreme Vegas escort negotiator. He is to Vegas escorts what William Shatner is to Priceline negotiations. The stories I hear are legendary and he actually wants to go out there with me. I figure I could learn from him. I am a decent talker with women, the result of experience, but this guy is on another level. I have seen him in action in strip clubs. He works in the financial industry and is used to talking and thinking on his feet with his clients and it just translates to a very effective approach in negotiating with escorts which is what you have to do in Vegas. It is a competition to get the best pussy for the least money, and he wins in those competitions.
Montreal is kind of easy. Lots of good girls for $200 and no negotiation is necessary. Vegas is not for the weak hobbyist. Bring your wallet and bring your negotiation skills or stay home.
Comparing Hobbying in Montreal and hobbying in Vegas is like comparing hunting Deer in North America to hunting Lions in Africa. If you miss a shot at a deer, he probably runs away. If you miss your shot at the Lion, there is a good chance you will be getting eaten.
