I have been known to put the odd slice in a gin and tonic. That reminds me...
Years ago, I was on a night out with a mate of mine (Actually, it was Elizabeth's husband, Ron) and we decided to go on the gin and tonics. Bars in those days seldom kept lemons so we took our own slices from pub to pub. It was interesting to see the reaction as we produced these increasingly ragged citrus slivers from the top pockets of our jackets, blew the fluff off them, and dropped them in our drinks. We was dead classy.
