Here’s how I typically rate my customers:
1-star deductions:
You’re not ready to go the second I pull up to the pickup location (my time is valuable, so I absolutely hate waiting for you)
You make little to no effort to engage in conversation with me (this isn’t a taxi)
You’re not clear with directions (I’m not about to make last minute turns or brakes because you weren’t paying attention to the road)
You slam my doors unnecessarily (pretty obvious)
2-star deductions:
You leave trash in my car (this is my car, not yours)
You talk loudly with each other (assuming there are at least 2 passengers) and are cursing left and right (keep your filthy language to yourself)
You start touching the radio/ac/heater without asking (again, this is my car, not yours)
3-star deductions:
You give me any type of attitude for anything (you should be happy if I don’t kick you out of my car)
I sometimes have more criteria, but it’s almost always on a case-by-case basis
