I was recently at this organic coffeehouse in town called Bridgehead, and made my first-ever acquaintance with a dual-flush toilet. Yes indeed... There were 2 buttons on the tank; one was a darkened circle and one was half a darkened circle.
How about that, ay?
A Don- inspired 3-egg breakfast? No problem: Press the darkened circle.
A couple of my double-strong Tazo iced chai tea lattes, with a splash of evaporated milk? Easier done than said: Press the half-darkened circle.
And god said let there be dual-flush toilets, and it was so.
...Anyone ever yet tried those toilets that, as I like to say; "return the favour"?
