It's also tipping season, and you'll likely lay out a hefty chunk of change for the servers at all of those celebratory meals, not to mention the cash that you'll stuff into envelopes for your super, nanny, hairdresser or other helpful professional. The etiquette around this can be tricky to navigate, so we surveyed 1,719 people to see what's normal, what's stingy and what's extreme.
