I’ve been stealing from my workplace for 5 months and I feel bad

I work at a movie theater and the policy is if you find unclaimed concessions left on a table you either throw it away or bring it in the back and let people eat it. This usually happens now since people don’t finish their food and just leave it. I’ve been taking the large popcorns and anything else I find back and eating it. I’ve also let some coworkers take some popcorn for themselves. I think if anyone else knows I’m doing this they’ll think I’m lazy but honestly it’s just so nice to have free food, it’s not worth spending my break finding somewhere to eat. This is the only bad thing I’ve done (to my knowledge) so I don’t know if I’m fired or not but just know I have a large popcorn on my desk right now and I’m eating it.
