In the US an upscale place would never bring a terminal to your table. They give you a check (receipt), you put card or money down, they take it to their register, and bring back a customer receipt or change.

Money is often a taboo subject in the US, and I think that is bleeding into a slow adoption of touchless transactions in nice restaurants.

It will take at least 5 years for this part of US culture to give way to convenience and security.
