My understanding is that Uber drivers are always happy about being uber drivers when talking to customers because there is a "secret shopper" program that considers complaining about the company to be a bad thing.
I understand why the company does it, but that's horrific. There was a sandwhich chain (mostly based in the UK) that even had a collective punishment thing - if someone at a shop was found to be insufficiently cheerful, everyone lost on the weekly bonus.
Yea in my experience they are rarely interested in talking about Uber itself. I always ask how they are finding it and they just say "yea good" or similar and move on.
