I'm watching live stream of DS, and I really like the options to use a paper menu or scan a QR code. I feel like they could expand this and have texting of questions and specials (which would be great for me because I have a problem paying attention to the list of specials) and orders. Then the only contact really needed for the server is to bring the food and drinks.
Lesson learned about not leaving food in the stroller.
and that was my first concern...
