Square Pickup - Accept pickup orders with Square

This could really help small restaurants handle busy times. There's a restaurant near me, where it's the just the owner himself doing all the cooking, waiting tables, taking take-out orders on the phone, etc. During busy times he seems to have a few other people to handle take out orders, but there's only one phone. Something like this could lighten the load a lot.

It's been exciting to see the efficiency Pickup has brought to beta merchants like http://SouvlaSF.com. Regular customers, who often order the same items, can order ahead, pay ahead, and just walk in, skip the line, pick up their order, and walk out.
