Head & a Latte

So long as all the workers, from waitresses to cleaning staff to the sex workers, are treated and paid well, as well as of course the customers come away happy with their experience, this sounds great. 

And, while not for me personally (I personally like to know my partners well before sharing secretions), there really ought to be a female equivalent.

But, hey, if everything is ethical and sex-positive, I'd be down to pay for overpriced coffee and the experience of witnessing the atmosphere.
