That's exactly what it's like in NYC. They just walk up with their huge backpacks straight to the front skipping everyone, turn around bumping people, show their phone, then stand RIGHT in the front as-if no one else exists. It's awful.
I'd love to contribute to a no-delivery store. Pickup or dine-in only.
Edit: Might have to re-think Pickup because that would just become a loophole for delivery. Maybe orders have to be placed in-store for to go.
