Go back, explain you noticed the plant wasn't paid for when you checked your receipt. Oh wait, you don't have a receipt. Offer to pay. They will just take your money and maybe thank you for your honesty.
It is unlikely the customer service people will even get LP involved.
Just so you know, yours is a story many shoplifters will try if they get caught. So if LP is around and you do something stupid like that again, odds are very good they are going to grab you up depending on what else they may have observed.
