carpediem I think you should perhaps spend some time in a nice pub. You seem to have very odd ideas about what they're like.
Pubs (believe it or not) are not all full of people getting steadily drunk at all hours of the day.
For Sunday lunch for example, many pubs have a very welcoming atmosphere, and the focus is on food and good company rather than getting bladdered.
May pubs down this way (Sussex) actually have brilliant play equipment like climbing frames out the back, and kids love going to them on warm days.
"The belief seems to be that exposure will socialise children into a more Mediterranean attitude to alcohol and that the social environment of the pub aids the teaching of good behaviour and manners."
I find this very odd tbh! If we decide to take a drive to a country pub for Sunday lunch in the summer, I'm thinking of eating some nice food, having one glass of a nice beer or wine, and whether the pub has a nice field or play equipment for the kids to run around in is a major factor.
Teaching the kids manners or a Mediterranean attitude couldn't be furthest from my mind! "Will the kids enjoy it, will the food be good?" That's what I'm thinking!
