Due to our shared ride nature, we appreciate if you let us know as soon as possible that you will not be needing a requested ride. This opens the schedule up for other passengers and allows us to serve as many people as possible. Once we have reserved a spot for you in our schedule it often prevents others from being able to be scheduled and potentially causing their trip to be denied. That being said, we kindly ask that you not use our service as a place holder if you have other transportation arrangements already made.
