I used to be a full time pizza delivery driver. We had other duties besides just delivering pizzas. Things that we'd do in between deliveries and at the end of the night after everyone else was sent home besides me and the manager. I guess I'd fit in to your example of an "employee doing double duty". We also got paid a lower wage than everyone else since we were expected to earn tips.

We once got a new driver from another store in the same franchise. I was blown away when I learned at his old store they would literally just stand around doing nothing or read the newspaper in their car, waiting for deliveries to take (getting paid the whole time). That's the kind of store that would save a lot of money by switching to Uber.

Thank you! I was so confused.
