I think the prominence of tip options is largely driven by the POS/payments platforms. Square, for example, wants you to tip because they get $.10 + 2.6% of the transaction. They would get this from the total transaction, so if you tip $2 they’ll get almost $.3 of that tip as part of the total transaction fee. They make it easy to enable for the vendor, but inconvenient to skip in the UI if enabled because you have to push a button to get to the receipt button. Plus why would the employee skip it? It might make them a little extra cash. The power of defaults is strong.
