I'm going to keep hacking the subway card vending machine.
Is that a way for you to get free subway rides?
Yes, I'm not paying for them if I don't need to.
That's the same as stealing which is wrong. Pay for your subway rides like everyone else.
Who cares if I am stealing? Anyways who's going to catch me?
The people who own the subway care that you are stealing. You could get banned from the subway and then you won't have a way to get around the city.
