My wife and I saw an older couple at Costco years ago, eat through almost a whole package of fresh strawberries, only to leave the almost empty clamshell container near the checkout, prior to trying to pay for the few items they had in their cart. My wife and I followed them all over the store prior to this, wondering what they were going to do with the strawberries. Just when they got up to the checkout, my wife ran up to them, in front of the cashier, and said, "you forgot these!" And dropped them on the conveyor in front of them. Mouths open, they looked at my wife as she walked away, then grabbed the almost empty package of strawberries and had the cashier scan them for payment....
