Anuj, what I had mentioned in the article is something I had come across on one of the many articles I went through as a part of some background research. Unfortunately, I did not save the link to the article and can’t find it right now. However, here is something I came across right now during my search for the original source. It seems to be a screenshot from a Uber driver-partner’s app. This should clear things up. Cheers.
