If DD didn’t exist it’s be someone else.. but if there was no delivery most people would pick up take out like before. I don’t mind paying a delivery fee. It’s kinda like the tip when you dine in person..
To be fair though, not all tech is similar. I don't think people mind Amzn charging the seller 5-15% and paying the delivery guys whatever it takes. I hope food delivery apps become more reasonably priced- or then maybe Amzn comes after their margin!
