Mum and Dad weren't big drinkers. However I remember that in the run-up to Christmas every effort was made to ensure that we were as well stocked with different varieties of alcohol as we were with food. Dad would wonder whether he needed to buy a fresh bottle of Cinzano while Mum checked that there was enough Lamb's Navy Rum to splash over the Christmas pudding. Then they would order a wide array of "splits", the small bottles of Schweppes Ginger ale or Indian Tonic that would be needed to administer drinks to everyone's requirements. They were terrified that somebody would ask for a Gin & It or Whisky Mac which they might not be able to provide.
Nobody caters like that any more, do they? I've just done our booze audit. We've got champagne, fizz, white, red and beer. Anyone who isn't happy with that can, quite frankly, whistle. Funny how while we've been growing fussier about food we've become less fussy about drink.
