this can only be enforce in brothels not escorts outside the brothel system i think
Not sure what you're 'thinking' matters here?
Example - even in the west end strip clubs known for most of the dancers providing extras in the back - kissing and bbbj were rare exceptions. Simply put, all the dancers has an understanding that those activities did not occur inside the club - if you want to provide that to a client, go for takeout and charge them a whole lot more. Been like that for years now.
Hence escorts, pre-virus speaking of course - were reducing the client base of the clubs more and more as gents seeking better value for their hobby dollars discovered agency ladies in particular. I know as I enjoyed both the clubs and escorts right up until January of this year.
Back to the OP's posting - appreciate the link as it shows what the industry may attempt to do - temporarily at least - to adapt and get back into business.
And yes canada-man - there will be escorts even in these areas where new restrictions are imposed/recommended/followed by most - who will 'break the rules' and offer pre-virus like experiences. This is no different than when bbbj was taboo among most escorts 8-12 years ago and then bbbj started to become more common and of course, look at where we were at in 2018/2019 before the virus.
