Well, that made forty-two marks for the week. Now the way to figure out how much the porteer ought to get is easy: a fellow I met in Baden-Baden showed me how to do it. First, you multiply your hotel bill by two, then you divide it by twenty-seven, and then you knock off half a mark. Twice forty-two is eighty-four. Twenty-seven into eighty-four goes about three times, and half from three leaves two and a half. See how easy it is?
