" In essence, the message was always the same, “I want one of those mixers of yours like the McDonald brothers have in San Bernardino, California.” I got curiouser and curiouser. Who were these McDonald brothers, and why were customers picking up on the Multimixer from them when I had similar machines in lots of places? (The machine, by this time had five spindles instead of six.) So I did some checking and was astonished to learn that the McDonalds had not one Multimixer, not two or three, but eight! The mental picture of eight Multimixers churning out forty shakes at one time was just too much to be believed. These mixers sold at $150 apiece, mind you, and that was back in 1954. "
