If you use the right detergent, you don't need to rinse the plates
Commercial dishwashers work a little differently. They're designed to clean fast and sanitize. They wash dishes in minutes, rather than an hour or more, like home units do. It might be different these days, but when I worked in a restaurant, you pre-scrubbed the plates before they went into the machine. They had to be somewhat clean going in, or food was baked on when they came out.
