Ah, I see. I'm a DINKY (or part of one perhaps?) and never even knew it. You learn something everyday. Cheers.
It's a fair point. People who haven't got (or are not going to have) children hate the little blighters being in there. After you have had them and they are weeing/shitting little bundles of fun or toddlers then you can restore some sanity in your life by being able to go and and quaff ale with them in tow. Once they grow up a bit and they are off doing their own thing you would rather go to pubs without children.
All part of life's rich tapestry and the lure of alcohol.
Personally I now hate pubs with children but then all of mine are in the 12 - 20 band and if we do go out for a drink and a meal we pick the middle range where our younger ones are allowed in but they (generally) act like adults and so it isn't a problem. Horses for courses.
