The other day, we were celebrating a friend’s birthday at a fancy restaurant. When the bill arrived, it was one of those big group messes where no one knew exactly how much they owed, let alone what the fair tip was. Some people had wine, others didn’t. The whole thing turned into a 15-minute discussion. Has anyone here tried a foolproof way to avoid this kind of chaos? Do you stick to splitting equally, or is there a tool that can help simplify it?
