Funnily enough, after commenting, I ended up getting Chinese food takeout at a place that have a makeshift pickup window. Looks to me like it was pretty cheap and simple to set up. https://ibb.co/Wv7ZYy1
A Chinese restaurant near me built a plastic enclosure at their doorway, with an airlock that they place the food into, before closing the door and letting you open the opposite door. It works great, although it was definitely non-trivial to construct.
