Between a guaranteed tip of a known amount vs a maybe possible tip, which would you choose?

That being said they're probably aware of the average expected value of a cash tip, and it maybe lower than whatever you guarantee via prepayment.

It's like asking if you want $10 or what's in the mystery box. You should never pick the mystery box as there is no incentive to actually put anything good in the mystery box.

Although if drivers hear about this story and find out that some prepaid tips are doing nothing for them, their perceptions of the cash tip may change. I figure they have the ability to give the customer zero stars if the promised tip isn’t given.
