Sounds like it's got all the makings of what a "proper" Pub
should be ! The combination of a barber's and liquid refreshment is a brilliant idea.
Bert's comment about the barber not being allowed to drink brings to mind that classic Python sketch... Shave, blood, cut, spurt, court case.....etc.
It's on the list for my next visit to the Wirral.
Best of luck Sue & Frank.
