Actually heard that a new LOE during 12m. You're climbing through 10,000 feet and receive a triple chime from the back. FA informs you that the snack basket was left in LAX. This will obviously be an air return back to LA. Heard a crew continued without the snack basket on board (really?) and subsequently had to repeat the LOE. Refer to the QRH. Black and white. Unless the snack basket is deferred, it's a land as soon as possible item.
