I am going to steal a fridge and give it back when the police ask.
Why would you steal a fridge?
Because I have a debt of 1,000 dollars and I have to pay it quickly
You should not steal things, regardless of your financial situation. If you are in debt, there are ways to negotiate payment plans so you can be financially independent.
I'm only taking it for a few hours, I just want to put it back.
Even if you intend on putting it back, stealing is illegal. If you need to borrow a fridge, I'm sure there are people who would let you store things in their fridge for a short period.
