Stop making the drinks

Just don't do it. That's not our job. As someone else here pointed out, we are couriers that pick up sealed bags of food and deliver it. We are not fast food workers and we are not employed by the restaurant.

Twice yesterday I was handed an empty cup and twice I said, "please complete the order" and twice the restaurant did. I would have refused to do the order had they not. I would have told them I would deliver the part of the order they did complete and explain to the customer that the restaurant refused to complete their order.

Not playing around. The restaurants know better and are trying to take advantage of the drivers.

Just stop. Tell them to complete the order. Don't do their job for them. Don't do it.
