When I was a teenager and me and my friends ran a successful scam to get pizza and other delivery food for free for over a year.
Why would you run such a scam?
It was a pretty straight forward thing, we found a marketer's phone number and pretended to be a restaurant. We were very convincing so the marketers never thought the callers were teenagers.
Well I hope you've learned since then that stealing food is wrong. You could have really hurt someone's business by doing that.
You are seriously overreacting, besides they are large mega companies which can afford to waste food.
It's never okay to steal in any situtation, even if it's from a big company. You should always pay for the things you want.
