My bad, I misunderstood, but I’m not sure how tips are relevant.

It seems like the GP(?, the first poster in this chain) was saying that delivery works for places like Domino’s which hires and pays their own couriers a standard wage. That wage is already accounted for in Domino’s pricing, and since that employee has to show up to work even when there aren’t deliveries they can be put to work. Thus, there are no additional costs to Domino’s as everything is presumably priced taking this into account.

When you outsource your delivery, the company being hired takes a cut. That company (Postmates etc) need to use this cut to pay their couriers. Postmates can only ask for so much before the store just says no, it’s not worth it. Those couriers need to be paid enough that it’s worth it for them to keep delivering. So, Postmates scales up to make up for it in bulk by taking losses by offering deals. Those deals don’t last forever, and customers like me only order because of the deals will just go away.
