So, let's expound upon that. Say your character isn't an alcoholic per se, but has a hard time not having a good time. The plan is that your character is staking out a bar to watch for a hand off between two rival agents. It starts innocently enough, having a beer to blend in. Then the attractive person sits down near enough to start chatting with. Soon enough the PCs is three drinks in and checking out instead of staking out. The agents meet and make the hand off and the character misses it.
Does this happen because the player failed a check? Does it happen because the player decided it should be cause it made sense? Did it happened because the GM said so? Was there a trade made -- say, metacurrency like Inspiration, Bennie or Fate Point -- for the behavior?
