i TOO , HAVE THAT TYPE OF SERVICE...i HAVE ONLY HAD A PROBLEM WHEN IT IS MEN BEHIND THE CAGE...

Usually , in Vegas (unless you are somewhere you dont want to be any way )they will go to the back ...or just tell you " NO"

The trick , is to "reward" in advance , the efforts , and you would Be SHOCKED at what a couple bucks upfront will reward you with.
