KEY POINTS
  • Fifty-seven percent of people tip 15% or less for a sit-down meal at a restaurant, according to a Pew Research Center poll.
  • Of those, 37% said 15% is their standard tip and 18% tip something less than 15%. An additional 2% tip nothing, Pew found.
  • Restaurant meals are the most commonly tipped service. When we tip, it's often due to social approval instead of service quality, one expert said.

When it comes to dining, tipping at least 15% to 20% is traditional etiquette, say experts.

It seems many Americans disagree.
