Abandoning the Shopping Cart: He Says She Says

(He sent me this photo from his phone while they were out, which is why she has no bow, and doesn't match.)

She returns with the baby after grabbing an item off their grocery list, and watches him push the cart toward the cereal isle. He parks the cart at the end of the aisle while he walks down to browse cereal.

She says: “Why do you just leave the cart there? Someone could take it.”

He says: “Why would someone want to take all of our stuff and buy it?”

What say you?

PS: I know the photo is misleading but he doesn't leave the cart with her IN IT (I hope). But when we're together he'll ditch it while I'm holding her, which drives me NUTS!
