I don't have pizza place that would recognize me by voice because I might order from any place like 1x a year or 2x a year.

I love that I can go to most of medium cities and I don't have to drive around searching for food places because I can find them via app, whether I stay with friends or in a hotel and just order food for evening.

Then calling on the phone in English is not really a good option, calling using broken local language might be even worse than trying English :)

Then payment before order with my app account and card is also super easy and convenient.

That said, I think it is not super common use case but that delivery app makes my life a lot easier.
