If it’s proper language you’ll be wanting, by blessed chance I’ve just come across “The trade”, an early (1940) essay on pubs by Myles na gCopaleen that has found a respectable home in the fine anthology Great Irish reportage.
This is the ultimate insider’s account. Pubs were Myles’s office and his home—seldom can ethnographers have had such an in-depth knowledge of their chosen fieldsite. He shows great sensitivity to change in attire and interior design:
The result is a combination of utility (functional something-or-other architects call it), comfort and restraint—but no pints.
In the last ten years there has been a marked change in the decor of boozing in Dublin. The old-time pub was something in the nature of the Augean stable (it is true that Pegasus was often tethered there) with liberal lashings of sawdust and mopping-rags to prevent customers from perishing in their own spillings and spewing. No genuine Irishman could relax and feel at home in a pub unless he was sitting in deep gloom on a hard seat with a a very sad expression on his face, listening to the drone of bluebottle squadrons carrying out a raid on the yellow sandwich cheese. In those days a genuine social stigma attached to drinking. It was exclusively a male occupation and on that account (and apart from anything temperance advocates had to say) it could not be regarded as respectable by any reasonable woman. Demon rum was a pal of the kind one is ashamed to be seen with. Even moderate drinkers accepted themselves as genteel degenerates and could slink into a pub with as much feline hug-the-wall as any cirrhotic whiskey-addict, there to hide even from each other in dim secret snugs. A pub without a side-door up a lane would have been as well off as one with no door at all.
