American consumers are feeling a bit of tip creep.
Leaving 15 percent for full service (the former standard tip at a sit-down restaurant), and less for quick transactions, is considered chintzy by some people. “We recommend 20 percent absolutely,” said Peter Post, managing director of the Emily Post Institute, which offers guidelines in etiquette.

Part of the reason for the general acquiescence to tip creep may be that Square is mostly a feature at high-end hipster shops — places that peddle what some might call “treats” and others might deride as “inessentials.”
