As you've mentioned steins and the small schnapps glasses, do you remember the schooner sherry glass, favoured by Berni Inns and others back in the day?
Dining in one of their establishments many years ago, I asked the good lady what she wanted to drink. As she wasn't thirsty and couldn't make up her mind (nothing new there), she saw the schooner of sherry advertised and asked what it was. Having explained that it was larger than a normal sherry glass but not as big as a half pint, she replied 'I'll have a schooner of lager then'. Aargh!
