Close but Not Exactly

Right after I got my eggs at the grocery store, I noticed there was a bag of Lays potato chips in my shopping cart. This was odd: I don’t eat potato chips usually. Someone must have put them in my cart. So I put them back on the shelf and went on my merry way, finished shopping and started unloading my stuff at the cashier. As I finished unloading, I realized that half the stuff wasn’t even mine. Where did all this stuff come from? Who would put a cantaloupe and all these radishes in my cart? Wait a sec . . . I reloaded everything back in the cart, went back to the produce section and found my original cart in its original spot with all my produce in it. I guess I grabbed a cart at some point that looked very similar to mine. But … wasn’t.
