A question of size

Well obviously, after so long an absence from the blogosphere, the very first things I want to blog about are bogs. No, I didn’t misspell that. Bogs.
Loos. Lavatories.
There’s something that has puzzled me for some time and after a couple of pints in the opera’s local boozer, the Blaubrug, and a couple of visits to the smallest room, I felt compelled to bring it up. So I asked Clive, our Claggart: “these loos with two flush buttons, which do you reckon you’re supposed to press? Is it small button for small flush or big button for big flush?”
