I remember a funny incident. A number of years ago, Louis stayed with me at my parents' home in Paisley, near Glasgow. We met a few Scottish folkies in the pub and Louis got the first round in. He asked each one what they wanted and, to a man, they replied "a hauf" (a half). He duly returned with a tray holding six half pints of beer and was surprised when he was greeted with cries of "whit's this?". What he didn't realise wa that "a hauf" in Glasgow means a half gill of whisky!
