I was careful stealing the items in my basket as I used the self check out option at the store.
Wow, that's no good. Do you know that stealing is against the law?
I don't give a shit about the law.
Shoplifting from a store is wrong since you are taking money away from the owners of that store. If you continue to steal via the self-checkout line at the store you will eventually be caught on camera and will be charged with shoplifting and fined or even be incarcerated. Having a criminal record will prevent you from getting a job and so you should not commit any actions that will result in a criminal record if you value your future success.
I'm not worried, so I don't care.
You may not care, but you will end up getting caught and then you will. Going to prison over stealing things just isn't worth it, don't you agree?
