I have read on forums that you should give passengers a low rating if they don't tip. well on the lyft app you don't know if the passenger tips you until sometime after you rate them. Wouldn't it be better for the customers rating if you gave them an option to tip the same way lyft does, even if they encourage the passengers not to tip? That way the customers ratings would no longer be based on tips. Just seems like it would be a win for the drivers and the passengers.
