As I've explained before, we have tips and tipping in all the occupations formerly occupied by servants. In America these were also occupations for blacks and slaves.
I have never seen a way to get rid of tips. Now I can.
When you use these services the tip is added automatically where tips are part of the occupation. Meaning, from the customer’s point of view, there is no tip.
My friends always cite this as an advantage of Uber. They dislike the emotions and rig-a-marole around tipping.
The smartphone apps have gotten rid of tips.
Now we get to watch this approach spread.
