"Tip creep" or "guilt tipping" is simply milking [1][2][3] the social conventions around tipping while you're standing in front of the would-be beneficiary, card in hand. Most of the tip goes to the seller, of course. But most payment processors deduct their fees from the total amount after taxes and tips, like Square does [4], so if the final transaction amounts are higher, as they are in this case, they make more money too.
