Most of the problem described here is the input mechanism. The building I work in has "destination dispatch" too but instead of a touchscreen, it has a large numeric keypad that you type your floor number on, with physical buttons that look like normal elevator buttons. We do also have some floors that are open to the public and i've only seen people confused by it a couple of times in several years of working here.
