Business Insider posted a guide for how to split the bill at a restaurant in a bunch of different situations. Here are different scenarios, and how they say you should handle them.

See if you agree:

  1. If you're on a first date, whoever asked for the date should pay, regardless of gender. Then take turns after that, or just agree to split it.
  2. If it's a business dinner, again the person who asked should pay. Or if they're your client, you should always pay.
  3. If it's a friend, just split it. But it's okay to ask for separate checks if theirs cost more.
  4. If it's a co-worker, just get separate checks and pay for what you ordered.
  5. If it's a group dinner for someone's birthday, the person who's celebrating a birthday shouldn't pay at all. Everyone else should throw in a little extra to cover their meal unless they organized it, and picked a really expensive place.
  6. If it's with a family member, use your best judgment. Parents, grandparents, and other relatives who are older might offer to pay for the whole thing. But don't expect them to. If it's a sibling, you'll probably just want to split it.
    And if it's your in-laws, go in with a plan. If they're visiting from out of town, you might want to pay. Especially if you're trying to impress them.
