A theme of "The Break" is that with selflessness comes great rewards. How do Faizula Turner's actions and interactions develop this theme?

Faizula Turner shows in his plane trip that he is a selfless and probably self-effacing individual as he doesn't put his seat back for example so assel not to disturb the person behind him even though somebody did that to him and forced his laptop shut in the process. In his reaction to a young man selling roses of buying one, he was invited to eat some snacks for the nightly food allowance during Ramadan, by the young rose seller so this shows how selflessness can be rewarded.
