Indulging a youngster or romantic partner will create an unfortunate precedent. Other people who have been working hard with no reward will resent all the gifts you bestow on this troublemaker. They'll stop performing their duties because they know they won't ever be recognised or appreciated. You can't risk creating such upheaval. Put your foot down the next time your impulsive friend starts trouble. Cancel a pleasurable outing or go out by yourself. Don't feel guilty about enforcing the rules. It's long overdue.
