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 ******** have is that they refuse tips when offered....which makes them not ******** but ******ed ********.
