Wait, don't drivers choose which deliveries they want? Or is that only Uber?
I thought it works like a ping goes out and nearby drivers decide to pick it up or not and see the tip beforehand.
That said, I feel bad when ordering long deliveries so I tip well. I actually asked on reddit before and everyone told me I tipped WAY too much. I tipped like 13 bucks for a 5 mile delivery, which IMO is pretty fucking far. And people were like dude, I'd do that for 7 bucks, 13 is insane, way too much.
So I cut the difference and now offer 9 bucks every 5 miles.
