This makes sense.
I like to eat, get my bill, and immediately. It's a restaurant. I'm there for the food. Why the fuck would I linger.
One of the things I loved the most in Japan is they bring you as soon as, or shortly after, you get your food. If you add more they just bring you an updated bill.
Or there's a machine at the front so you can just pay before you leave. You still have the bill though.
Like. Fuck. It was like being in heaven.
