For a while Meatball Shop (a New York mini-chain of, well, meatball-focused bar/restaurants) was doing this for takeout orders placed in the restaurant.
I'm not sure if they still do, but it basically meant whoever was the poor person assigned to the takeout counter that day had to spend at least half their time dealing with people saying "Why do you need my phone number? I'm right here!"
I think they said it was to track customers' ordering patterns over time, which was interesting, but also kind of overkill (and probably misleading, since they wouldn't know when the same people sat down to eat in the restaurant or at the bar).
