I think Targets have a reputation for being rude asses (at least from the stories I've heard, and what I've experienced). And I understand they don't know everything about every item in the store (I'm a cashier at Wal-Mart, and I don't know a whole lot). But you don't have to be an idiot to know that each individual MLP have names, and when a customer calls asking if you have ______ and ______ MLP babies at the checkout stands, you don't just glance down the isle and think Oh, there's some babies - yep, we've got em!
I hope that makes sense. What I'm saying is, the employee should have at least looked at the babies in the checkouts, to see what their names were. If it were me (calling Target), I would have emphasized that the babies have scarfs.
