When you collaborate, it's nice if everyone on your team gets along, but there's a problem with agreeing on everything: No new ideas. This is also called "groupthink". To avoid it, don't be afraid to disagree.

Figuring out the bill after a group dinner is tough enough without having to cover those who left early and accidentally miscalculated how much they owed. Settle the dinner bill when they leave to avoid having to awkwardly ask them for more money later or overpaying at the end of the night to cover them.
