Dominos is arguably quite a bit larger than the mom & pop restaurant I did delivery for, but... for us it was break-even or a very tiny loss. I don't remember exactly the number, but delivery was $5; $5 charged to the customer, $5 paid to the driver. I think it was waived for large orders (>$100?), but those were pretty rare. Tips were all for the driver as well. On a good night, you could make $20-30/hr; on a holiday night (New Year's Eve was my favourite), it'd be more like $40-$50 once you factor in the tips.

Was it overall a living wage as a sole source of income? No, not at all. There was usually only a small window every day when people actually wanted delivery. Was it good money for the number of hours worked? Sixteen year-old me sure thought so!

Delivery is profitable for dominos. But the real money, well that is in garlic bread.
