The main difference is that the pizza place hires the delivery person, and all the carryout folks were subsidizing it. The price for carryout and delivery is the same, except I have to tip the driver, and I know the driver keeps the whole tip.
There is no middleman sucking a bunch of money out of my community.
>Amazing that people have normalized paying for the insane number of fees plus tip to get one thing delivered.
By the same token, you can ask why people eat out in restaurants given how much more expensive it is compared to cooking at home. I take your point about the expense though. If you habitually get delivery, it will add up to significant sums .. but then again, so does eating out.
