I live in Philadelphia. I've done quite a bit of rides to Newark, NJ airport which is about 85 miles away, 1.5hr drive in one direction. They've all been regular rides, never got any premium or XL requests for that distance. When they tip about $20 it makes the fair decent because I have to drive 85 miles back to Philly plus pay another $10 in tolls. Of the rides I've taken there, about half the time they tip, the other half they don't. I'm considering requesting an up front cash tip of $30. I've never done that before but its either that or just decline these requests from now on. What's Uber and Lyft's policy on requesting up front cash tips? Is it OK to do so? If you request up front cash tips from your pax, how do you say it to make the passenger understand why you're asking for it? How often do the pax agree or disagree?
