IMHO, this isn't a new phenomenon. Close to 18 years ago, I lived in a city with a popular pizza spot that was about a 10 minute walk away. Normally I'd walk, but having a newborn make that challenging, so I'd get delivery.

Typically, the delivery would take 60+ minutes on a busy night, but after a few consecutive Fridays of a decent tip for the order, the pizza would arrive "burn your fingers" in about 20 minutes.
