Ray crock made his living selling the five spindle multi mixer milk shake machine out of chicago. In 19 54, he began hearing about a hamburger stand in san bernardino, california. This particular restaurant had no fewer than eight of his machines in operation and could make forty milk shakes simultaneously. Ray crock can't believe how good they are. The macdonald's french fry was in an entirely different league. They lavished attention on it. And once they folded, everyone else did too.
