Fast food joints outsourcing the order takers
I was just watching a thing on fast food tech that talked about this. Basically, they're experimenting with centralized call centers manning the order taking end of drive-thrus, then sending the order to the restaurant's kitchen.
I think this may be one of the best applications of outsourcing I've seen. The point, in part, is that for order taking you hire people who speak perfectly clearly, which is nice. Plus the workers in the hot restaurant don't have to wear a headset all day, and overall noise in the restaurant is reduced.
