I hate tipping. It's an unwanted cognitive intrusion with no upside for me whatsoever. It also reflects a broken (wage / reward) system, and obviously my preference is they fix that.
In Australia I may tip - iff the service is really good. And only at sit-down / eat-in restaurants. Cafes, cabs, ubers, couriers, hotels, etc - these are not tipping places. If I'm tipping at a restaurant, in addition to exceptional service / food, it'll be a) only if I feel there's zero guilt or implied obligation to tip, b) 5-10%, and c) cash (ie. not via the EFT / POS device).
