I&#x27;ve thought for a while that restaurants should have kiosks where you swipe your ID&#x2F;card&#x2F;whatever and it has a list of your preferences for the waiter&#x2F;waitress, such as the fact that I always order water (no lemon!) to drink, so they can improve their service by just bringing that without asking.<p>Add in allergies, favorite orders, and more and you&#x27;ve got a lot of info about your customers to help you make them happier.  Plus you get some lock-in because they don&#x27;t want to have to enter all that info into a new restaurant&#x27;s system.<p>I think this is the fast-food version, and that more restaurants will follow.
