I'm wondering about others that have gone this route too. I have only agreed to these when actual riders is slow but so far it doesn't seem to pan out money wise. Between waiting at busy restaurants and no tips from the people, I'm waiting to see how UBER keeps drivers doing this. Deliveries have ranged from apartment complexes to houses, with the former requiring a certain amount of extra navigation depending on the place. Last night, I may have actually lost a little money trying to eats between rides. Has anyone had success doing this?
