The ONE time I ordered from Door Dash, they recommended a tip based off of the distance...
They recommended I tip the driver $4.
On about a fifty buck order.
Yes, I was having him deliver it a distance he could walk because pandemic.
I was horrified, added a proper tip, and haven't used Door Dash since. I would have happily tipped MORE on a longer distance to help cover gas, but there was no way I was tipping $4 to an essential employee in the middle of a pandemic.
I'm unsurprised there are other terrible things going on. The form was set up so that anyone in a hurry would just have tipped the recommended amount.
