I wonder if the fruit bill is because he took it from the commissary. If I remember correctly, the Bethelites have to pay for things from the commissary anyhow. It's not like the buffet food that they can get for free.
But still it takes a lot of nerve to invoice an out-going bethelite over such a trivial thing.
He has had some harsh treatment, and there's undoubtedly more to the story.
