This last current week, I picked up two drivers on purpose thinking they would be tippers. I believe the first one was on Monday from the coastal area. I told him about this site and talked about teaching him how to do "skipping". SOB didnt tip so I gave him a 4 star. ALL DRIVERS SHOULD BE TIPPING THEIR UBER DRIVER! So last night I am skipping probably 10 pings as I am trying to get that Orange to Red but drivers still taking these $1.10 fares. I end up seeing a driver and think, "it isn't surging but if I take anyone, I should take a driver and make up the fare with a tip." He is at 4.71 but I know that is driving not riding. He doesn't take the ride but a friend does on his account. When I pulled up, he was outside so that was positive. I told him I skipped a whole bunch of calls but took his knowing he was a driver. The friend directed me away from WAZE but I swallowed my Waze pride and took the directions which was fine. No tip either! Gave a 4 star again and now I am pissed. Both riders, as drivers, can see their rating instantly and then retaliate against me. One gave me a 1 or 2 and the other gave a 4. As many of you guys know, I only do 1 or 2 rides a day as I cherry pick to go towards my office or towards my home. So I can tell when the rating came in a lot better than if I took a ton of rides everyday. No more! Screw drivers and sad that they are as cheap as the PAX we pick up. Only excuse these assholes have is that they refuse tips when offered....which makes them not assholes but ******ed assholes.
