Food Delivery is a First World Luxury - meaning that it's the only scenario in which the system functions reasonably (aka it's inherently expensive, a true economic luxury). Food Delivery is Cheap in places where the system is completely defunct, it's not a luxury it's a sign of failure.

Agreed with this statement. I've lived all over the world and have seen the wide differences.

I still remember living in a large suburb in India (not in the city; people had cars). We sat down for dinner and I asked if they had any ketchup. The host picked up the phone, spoke for 10 seconds, and 5 minutes later a boy knocked on the door with nothing but a single bottle in his hand. There wasn't even a grocery store close to the house that I could see.

Never living in any top-rated US cities have I seen anything close to that.
