The food was already sealed and safe for travel. Can't recall clearly, but I think it was some dried fish or sausage dish. So it was just a manner of getting it delivered. She ordered a lot and didn't want the hassle of us lugging it with us during the remainder of our day.

Still, impressive nonetheless.

The German Railway used to deliver packages with the regular high speed rail system. You bring it to the train, it gets put in a cargo room, and you arrange for someone to pick it up at the destination station.

It was expensive of course since it was the fastest way to move stuff (trains are faster than cars), but I imagine that at cost it would be cheap enough for takeout.

They still have a courier service:

Delivery can also be done to Paris, Vienna, Basel and Amsterdam along with the ICE trains travelling there.

Prices I'm shown ~0,22 EUR/km, 33€ to and from the station each and a surcharge of 33€ for night or holiday transport, so ~300€ for crossing the country, and it takes less than a day. Maybe there are rich people out there paying that much for takeout?
