Sorry to say the maps are not accurate and following the GPS is also like driving in the maze cos you might not know, the drivers version of Waze and you version of waze is slightly different routes.

I always make it a point to confirm with the customer the location before I start and when I'm near to its location, so far all customers are helpful.

And when picking a ride, always make sure his location not far away, he will still pick it up cos if he doesnt then his acceptance ratio will go down.
I also will pick all request even though far, and then call the customer to cancel cos its just too far.
Cancel booking for no reason sometimes happen. No need to get stressed, if you no time, better dont take Uber/Grab. Just an advice.

If you cancel, their AR will increase to meet the min requirement
