Paddyann Here on the Emerald Isle we would have the same attitude to alcohol as in Scotland, possibly a Celtic trait.
My friend and I often discuss this and had similar happenings when growing up i.e. if father wasn't home within a half hour of finishing work then he wouldn't be home till after 'closing time'. Women got their housekeeping hopefully before it all got spent in the pub.
Going back some 60 odd years much work was more labour intensive, done outdoors in horrible weather, and I can see how the camaraderi (sp?) of the pub with workmates might appeal. Not saying it was the right way of doing things, it's just how it was, as I recall it.
As for not being available 24/7..... hmmmmm... not so sure about that. There was always the pub with the back door at 9 in the morning. The lock in 'after hours'. As long as there was no trouble a blind eye was turned most of the time.
