Selfish

The young waiter in the story reminds me of Horace from the Ranger's Apprentice 1. These two are both self-centered and they don't know the consequences of their actions until it's too late. For example, the young waiter tells the old man that he should have killed himself just because he wasn't going to leave the bar and he wanted to go home. Horace betrays one of his peers and ends up getting themselves captured and his peer killed.
