I've learned after reading threads here and on Reddit that on the mainland drivers rate riders down if they don't tip. Yet it seems that every pax I pick up is rated 5 stars somehow and only one out of 10 rides tip. Often riders tip days after the ride, and many times hours after the ride. Obviously most of our riders are international tourists so our market is unique. Is there a way for us to use that rating system here for our benefit? At this point I'm prompted to rate the rider immediately after the ride ends and I don't know if I will receive a tip or not- very few pax tip cash. It seems like in some cities the pax are scared not to tip because they don't want their rating to go down.
