No stops on base rate rides unless they give CASH UPFRONT.
No "I'll tip you in the app" bullshit. Paper with dead presidents on it. Minimum of Lincoln's portrait or multiple Washington's ortrait.
Simply say "I only make money when my wheels are rolling" and either they'll get the hint and pull out cash or you end the trip as soon as they exit at first stop.
Do NOT let them "anchor" you by leaving items in the car.
Don't GAF about the occasional 1*. You pay your bills with money not ratings, stars and badges.
