Yeah . . . but . . . . it also sends the message back that you aren't into what he wants - so he (if it was me) would just get up and move on to the next possible donor. An exception, of course, is a dude who wants to do both give-n-take. The thing I look for, if I'm suspicious, is whether or not he works his junk. If he just stands or sits there on the other side of the GH and does nothing - the most I will do is give the finger signal. I have found that some str8 curious guys really have to be "encouraged" and will wait for an "invite" before they do anything. If he still sits there with no action - I get the hell away from him. In my many yrs of gh patronization . . . I've only run into a few men who are just legitimate voyeurs. Just watching is all they want to do. I know it's "a thing" but still find it suspicious and just plain creepy.
Mohave County, AZ is the most lenient legally toward ABS's of any place I've every been. Shortly after I moved to Bullhead - I was at the larger store there on Hwy 95 one afternoon when they had carpenters "customizing" all the booths that didn't already have gh's. They even asked me to step up to one of the walls so they could measure and cut a gh convenient for my height. During the time I was there - I ran into a fireman and another govt official who told me the attitude the City/County had was that they would rather have the "action" confined to ABS's between consenting adults than in the parks and on the streets. Makes total sense. I was there for 14 yrs and never heard of any legal situations. I sure do miss the convenient Arcades.
