Don't reward bad behavior. It is one of the first rules of parenting. During the financial cataclysm of 2008 we said it differently. When we bailed out banks that had created their own misfortune we called it a 'moral hazard ' because the bailout absolved the bank's bad acts and created an incentive for it to make the same bad loans again.
And it is very sexy as well: somebody says I'm taking you on a surprise date you don't know where you are going and you can't see and then you put your hand out and there is a tiger. Amazing.
