I don't mind grumpy or depressed passengers. I don't like the wealthy passengers the treat me like the butler or servant. Uber is not that kind of service. I'm a regular person sharing my car with them, not the shoe shine boy. Weirdly, I only got that in San Francisco.
The shoe shine boy is also a regular person.
Sure, but it's a question of status in society and how you are treated according to your status. A butler accepts money to be subservient to their employer and attend to their needs. An Uber driver isn't like that. He or she is captain of the ship navigating a vehicle through sometimes difficult circumstances and if the passenger doesn't like it, they are welcome to get out.
