While the drones won't mind working at night or on weekends, I would certainly mind the relentless, high-pitched noise of drones delivering groceries and the latest new tech gadgets to my neighbours when I try to sleep or relax.

Honestly, I dread the thought of hundreds or thousands of drones buzzing around the city on a daily basis. It's already pretty bad at many touristic spots because everybody needs their own little aerial video that nobody will ever watch.
