What is the theme in Last Orders by Graham Swift?

The themes of fate and obligation repeat and intertwine heavily in this story. Fate plays a major part in Ray's life, as he routinely makes major life decisions by wagering at the track (if it's a win or loss, I do this.) All the men have strong fathers who push them in varying directions. Where Ray's father is proud that he actually escapes the family trade, Jack and Vic never really seriously considered not following in their fathers' footsteps. Although both resigned to their fates in some manner, these two men take their obligation and inheritance differently. Vic grows to enjoy his trade. He sees the power he has and the righteousness of his compassion. He is proud that he doesn't take advantage of people in their weakest moments like some of his competitors. Vic is truly happy as an undertaker.
