I’d like to point out that restaurants can customize the default pct amounts to tip, and it’s a hassle in the moment to click “custom” then type in either a dollar amount, or your own percentage, whichever the POS system is designed to show. (Lately some places set the options to 20% as the minimum, as the article says) You don’t know what you’re going to get. The server can tell if you’ve tapped “custom” because it’s 3 or 4 extra button presses, whereas the default amount is one tap.
