According to this excerpt from Levitt and Dubnerâ' s Freakonomics, the definition of crime is subjective and depends on who commits the crime and what type is committed.
The correct answer is B (the second one).
What the author is explaining in this excerpt is that the worker that is failing to pay for a bagel, which means not paying for what he is taking and can be considered a minor crime, is very unlikely to leave a restaurant without paying because he or she will consider it an actual crime.
Although in both cases the worker's action is essentially the same (not paying for what he eats), one is considered not important and the other one is considered a crime.
