Do you have to pay for other people's drinks if you didn't order any? Do you chip in for an appetizer you didn't eat? How do you split tax and tip?
So starts the CNN story about splitting the check (without losing friends). The social etiquette of group dinning may be evolving due to the advent of smartphone payment apps like Venmo and Square Cash that allow funds transfers among friends. Moreover, apps such as Tab or Plates are specifically designed to split the check using these funds transfer apps.
It used to be that when I initiated the invitation, I expected to pick up the tab. Often, there was an expectation of later reciprocal invitations which helped facilitate the development of longer term relationships. Sometimes though, it encouraged free-riding as they ordered from the top-shelf. But if it is easy settle-up after each shared meal, both reciprocation and free-riding are reduced.
Paying only for what you ordered -- particularly down to the cent -- used to feel stingy. But the apps help reduce the pressure to round up or kick in a little extra.
