I think you'd have to have nerves of steel as a company to try either of those maneuvers. The wind can be unpredictable so close to a structure, it is a cramped environment filled with objects and materials you can't predict, even a meal for 2 can be kindof bulky (doubly so bc it has to be packed well enough to be airworthy), the load might shift internally, and if you screw up there's a good chance a drone goes plummeting 20 stories down onto a crowded sidewalk.
