I was thinking...when a pax first sits down in the vehicle they should be a 3. Neutral. An average person. If they do something good then it goes up, if something bad then it goes down. Why should everybody be a 5 or a 4? It throws everything off. If a person getting in is a 3 then that should be ok. If a 4 or 5 then better still and maybe I'd make more of an effort. If a 2 or 1 then I'd say what's up with you? But no, if we see a pax with a 4.3 we think it's bad.
