Ever since Thomas Crapper invented the toilet, flushers have come in a bewildering array of forms. They can be pull chains, foot petals, or any number of weird buttons.
Thomas Crapper – Inventor of “The Crapper”
I like frugal people, and I have noticed that people in Europe will always turn a nickel over twice. The thriftiness of the Scotch and Dutch is legendary (e.g. the “Dutch Treat), and I noted that their toilets have two buttons, with the intent of saving a few micro-pennies per flush.
If European, you press the light flush button. Anything weighing more than five Courics (1) requires the “heavy flush” button.
