A Reader Question: What goes in your G&T?

A reader question: Dear Muffy, On the assumption that I'm not the only one of your readers that enjoys a gin & tonic, what is their favourite "slice" or for that matter "wedge". I personally prefer lime, but I have a dear friend who likes orange, which is not something I've seen anyone else do. If it's not lime, it's usually lemon. Any thoughts? Kind regards
