My experience, here in Ottawa, has been that most providers only offer location during an immediate pre-meeting phone call. Doesn't offer complete discretion but does limit the risk of that being easily and inappropriately shared.
At this stage I'll choose not to comment further, (oh yeah, I've got waaay more thoughts on this but they stray too close the edge of lyla rules) so I'll simply post two video links: one from Arlo Guthrie and the other from the Canadian treasure, Willie P. Bennet. I've shared WPB with Greenteal before but the message hasn't been recognized. Willie and I shared harmonicas at the Ottawa Folk festival back in the late 90's (something that doesn't happen these days!) : Anyway two good questions to address. I know where I stand. I do, and always will, stand with my sex worker friends
