"Naturally. That's the tip fixed by custom. You may almost say it's the unwritten law. If you gave the conductor more, he would hand you change. Well, how I reason it out is this way: If five pfennigs is enough for a car conductor, who may carry you three miles, why shouldn't it be enough for the elevator boy, who may carry you only three stories?"
"It seems fair, certainly."
"And it is fair. So all you have to do is to keep account of the number of times you go up and down in the elevator, and then give the elevator boy five pfennigs for each trip. Say you come down in the morning, go up in the evening, and average one other round trip a day. That makes twenty-eight trips a week. Five times twenty-eight is one mark forty—and there you are."
"I see. By the way, what hotel are you stopping at?"
"The Goldene Esel."
