For those abroad, even the notion of tipping can be absurd. Using that notion as a point of support for a payment system the levies fraud responsibilities onto the merchant and is very easy to circumvent, and the reason most other places moved to chip+pin, or contactless a long time ago is even more amusing.

I understand what you're saying, and how its locally relevant, but from the outside looking in the US is a long way behind on keeping up with the tech in this space.
