This is a pretty privileged take. Not everyone who can afford to buy Subway for lunch can afford to pay 15% more for it. Tipping has become contentious lately because it's been asserting itself as an opt-out part of every Square checkout flow, even in situations where we never used to tip like fast casual order-at-the-counter. In the era of Uber we're also frequently asked to pick a tip before we even receive the service, which feels more like extortion than "something nice". Tipping is becoming more and more contentious because tipping is changing, and the version you describe is quickly becoming the minority case.
