Personally, I like to see everything a game has to offer. Just like when I first buy a game, I'll sit through the title screen loop to see what it has to offer, and I run around exploring EVERYWHERE in a free-roam world to see what it has to offer, I'll sit though the credits to see what they have to offer. If the credits are visually unappealing, the music is usually okay and I'll do something else while watching the credits (I always have my computer on).
I'm generally patient (everywhere in life) because good things usually come to those who wait (or rather, don't rush it). I think that's best summed up in The Getaway's thing where in order to heal you have to wait against a wall - you wait, you heal, it's good (though I really hate Yasmin yelling my ear off over it).
