In a similar vein we were drinking well after hours in an Irish pub, just over the border in the Republic. Sunday's the big drinking day and I think Fermanagh in the north was, at least back then, dry on sunday so loads had nipped across so the pub was packed. A very drunk old farmer was semi conscious leaning against the wall in the corridor and eventually his two strapping grown up sons, came to fetch him home. "C'mon da, time to go" and the carried him out to their landrover.
Astonishingly the comatose old man was shoved into the driver's seat and the two sons climbed in the back !
I understand drink driving laws are taken considerably more seriously these days
