Should I give this old spoiled food to the police officer?
That doesn't seem like a good idea. Why would you want to give them rotten food?
Because I don't want it, and they should be grateful I am offering them something for free!
It's not a good idea to serve anyone spoiled food. It might make them sick or kill them. It's best just to throw the food away.
Fine. I'll toss it.
I am glad you changed your mind! You will feel better not having to live with the guilt of potentially making someone sick by giving them spoiled food. You are making a good choice by throwing the food out instead.
