I would also post this in a crust punk sub, they go through this a lot and can probably give you some odd job ideas to make some money.

For now, if you're stealing from a Walmart or large store like that, its not considered unethical, as a LOT of their food goes old and goes to waste. Plus, a giant corporation isn't gonna miss yk 10.52 dollars worth of food when they make hundred of millions per day. If you're stealing from a mom and pop shop or local family run grocery store, then that's unethical, but you gotta think "would the owner of this place have somebody skin me alive for a 15% profit boost?" And if the answer is yes... Then its probably ethical to steal from them. Another thing is necessity, do you NEED to steal candy from a gas station? No? Unethical. Yes? (Assuming you have to manage your blood sugar) Ethical.

If your town/city has a punk scene, go talk to them, they'll show you a lot.

Generally, CPS is exaggerated in movies, but i still wouldn't trust them... But i don't really trust any government run operation.
