I&#x27;ve worked as a server and I thought this was going to focus on POS systems and how horribly they are (often) implemented. Talk about a design nightmare, with at least 5 clicks to put in one person&#x27;s order (x2-4 for a typical table). And items were almost always in a random configuration with little reasoning for placement of, for instance, extra mayonnaise versus no lettuce. I&#x27;m not sure if the new mobile POS systems are any better, but I will never forget how bad restaurant POSs are when designing UIs.
