So in your advocacy of tipping, your foremost argument is that it is not prohibited. You understand that tipping Uber drivers is inconvenient by design and contravenes custom, yet you insist that non-tipping customers are hypocrites by way of imputing us (baselessly) as adherents of a philosophy that customers, not businesses, bear responsibility for the livelihood of their workers. You deride us as cheapskates -- that is your prerogative. I continue to believe there is nothing cheap about using a service in accordance with expectations and social norms.

If the day comes that tipping is customary on Uber, I will tip, regardless of how much my driver otherwise makes.
