Do you guys converse? What's the protocol for this? I normally greet them, ask them for their name, verify their destination. Then I go. If they appear friendly and want to talk more, I do my best to maintain a conversation with them. If they don't say anything, I won't either. I'm getting the occasional 1 star or possibly a bunch of 4 stars but most likely the 1 star. I had a 4.91 in the last 50 rides. Then today it dropped to 4.83. I don't think I did anything to deserve it. Any advice? Does this happen to everyone?
