You don’t have to lecture your friends. Just be the one who says “let’s grab food instead” at the right moment.

Friends almost never change direction because somebody made an argument at them. They change direction because a plausible alternative appeared at the moment the current one was wobbling. Providing that alternative is a small act of steering that nobody experiences as being told what to do.

Notice the moment a night is about to tip somewhere you would rather it did not, and offer a concrete replacement instead of an objection. Have somewhere in mind beforehand. Friends will follow a specific suggestion far more readily than a warning.
