How do you reason this out with the pax? I'd be telling them that the app won't pay me if it see's that I've marked arrival at wrong waypoints along the way...
Things you can say. Take your pick. It will depend on if you are literally stoping on the way, or following a paxholes description of "on the way" which can be many KMs of diversions
Have you ever had the app say your driver is 3 mins away, only for them do drive in the opposite direction. With the arrival time increasing? This is one reason. You don't want the next trip you accept to rip you to pieces when you arrive.
Mention FUbers insurance coverage that no one has ever seen.
Following the pax directions could mean they get overcharged on a fixed fare if it ends up shorter. Maybe increase the fare if it breaks. You don't want FUber fare disputes. You just want to get on with driving, not dealing with their support.
If they are rude or you sense they are gaming you, accept you can't win. Play dumb. I've said to plenty of paxholes, if it's on the way, I'll follow the navigation. Just let me know when to apply the brakes so they can safely get out along the way without diverting.
Pull over if they play dumb and give advice on how to edit the trip. Most paxholes just want to get home. They will update if they know they are going to be delayed and are trying to get something for free.
Be creative. Stand your ground. Be pleasant but firm. You might need to give in on the rare occasion.
Basically read the situation. Be nice. Failing all of the above, end the trip. Before you do let them know they might get assigned a driver 15 mins away. 👍
