It’s part off doing business. A frustrating part, but a reality of rideshare. Think if the scenario were turned around. What if we, as drivers, collected 100% and were responsible for reimbursing LYFT 20%. Further assume that this was based on a flat fare the customer is quoted. Mathematically, if the quoted fare was $10, but the ride ended with a payment of $20 (traffic delays, road construction, destination change, etc...), Would you reimburse LYFT $2 or $4? I am not defending LYFT or justifying their method. It is what it is.
