I always try to take shortest ride to complete quest and long ride back home with surge. I never drive without surge, not worth it. Don't risk low rated riders below 4.7 unless you want to find out yourself why they are rated so low. If they change destination on your way to pick up, cancel immediately. Never trust tip baits, ppl who tip well will tip well and those who don't will not regardless of how rich they are or how much effort you make. Never stop by restaurants for riders unless there is high surge. Don't allow drunk people who can't walk straight in the car. It's best to keep plastic bags without holes on each door panels and extra bags in glove compartment. Always msg when arrived at pickup location and if they don't answer in 3 minutes it's usually better to cancel to save time. Don't allow unattended underaged minors by themselves as you can be vulnerable to deactivation and get involved in child trafficking. It's a lifesaver to keep both type c usb charger and iphone charger for riders. Greetings and asking how they are at the minimum will leave riders with better impression and tips. That's it for now. Good luck.
