That's very true Di, there was a culture of lunchtime drinking - my first job was for the DHSS in Government Buildings in Acton in the mid to late '70s. We shared the premises with MOD, Admiralty and others and there was a huge canteen there and a subsidised bar. We all sat there drinking and smoking at lunchtime - then went back to our desks and worked. I was telling the young girls I worked with at Osprey about this a couple of years back, but they thought I was pulling their leg - Not only drinking allowed in working hours, but subsidised drinking in a work's canteen bar? Never!!!!
Like Di I don't remember anyone being admitted to hospital in those days through drinking, yet two of the little girls I worked with recently at Osprey had, and didn't seem to think anything of it...
I'm not sure about the happy hour business, from what I gathered working with such young girls and listening to their plans and gossip, they seem to drink at home first - a lot, mainly wine and cider or beer, tanking up on the cheaper stuff - whilst getting ready for a night out, then go out very late on to clubs and such to drink shots and spirits....
We went out to have an enjoyable evening and if we got drunk, well then it happened but it wasn't the main intention. These days getting drunk seems to be the aim, and if you don't get legless you haven't had a good time. A definite sea change I think......
