Most standups are therefore tea parties. A previous boss of mine even used to bring biscuits, which was nice. It serves the role of reminding everyone that each other exists and are collaborating as a team, which occasionally needs reinforcement.
It's an RAF forums in-joke that being invited to a "meeting without biscuits" means you are going to be reprimanded.
