This is why I mentioned square, not stripe. Anyone acting more like a utility or common carrier. Stripe is good, but there are many other comparable options out there. But my local coffee shop only uses a single POS systems. The latter seems more sinister to me, especially since they would be taking an action that is potentially independent of the their customer (the business).

For stripe, the example would be refusing to process any CC payments (as a consumer) for registered republicans whatsoever. Beyond it being foolish commercially, it is much more intrusive than a refusing a direct 1:1 contract.
