Secret Treats at Work

So I work at this big grocery store and one day, while stocking the candy aisle, I noticed a case of my favorite chocolate bars that was about to expire. The manager hadn't taken it off yet, so I grabbed a few extra packs for myself. Then I thought, why not? Might as well take some for my coworkers too! So I snuck into the break room and hid them under some old snacks. That night, when I got home, I opened one up and it was amazing! But now every time someone walks in, I get nervous they'll notice the empty spots on the shelf. Should I confess to the manager or keep it a secret? Chocolate calls my name...
