  // this method serves kitchen subsystem and waiter subsystem requests,

  // is the same for kitchen subsystem and waiter subsystem,
  // meaning that the request URI is the same (according to REST).
  // You cannot have two methods with the same request URI mapping.
  // It is because the "event" request parameter (which is the distinguishing
  // parameter) is part of the HTTP body and can therefore not be
  // used for the request mapping.
