"But my gripe is with the attitude of some who think that there's some sort of need for the type of 'adult pubs' that I describe, and in particular I'm annoyed local authorities using licencing to ban kids from pubs after a certain time (usually 9pm)."
Isn't in the interests of the children not to be kept in pubs after 9pm?
I don't quite understand the basis for your objection.
Also children have playgrounds - and so adults also need an adult only space after a certain time in the evening. I don't see anything wrong with that. Why would you want your child to be sat in a pub at 10pm anyway?
