The only way to order from Dominos is to use coupons, and even them I feel like I always spent more than I intend to. I remember a handful of years ago they were putting flyers on the pizza box saying that the delivery few doesn’t count as a tip. Then what’s the delivery fee for???
In the US, delivery drivers are paid below minimum wage, not to mention they’re usually using their own cars, so it is expected to tip them to make up the difference. The flyer was saying that the delivery fee doesn’t directly go to drivers, if it did then the tip would actually be optional.
