I live in a small building without onsite management. No rules around deliveries. I prefer delivery to my door. I live close enough to the building entrance though that I'll often meet them down there.

In my experience the delivery people are in and out as fast as they can. They're not hanging out committing crimes.

If I were you I'd buy my own insulated bag and meet the delivery person in the lobby. Less convenient for sure but you'd be able to keep your food hot.
