Why even sign onto uber X/Pool platform at all when you drive a Suburban LTZ? Even to avoid the dead miles that car is too nice for any rates below XL. Not to mention that pax is going to start expecting suburbans for X/Pool prices now. I had a family of 6 call me for X last month. Said the last 3 UberX they got were SUV so they didn't want to pay for XL since most drivers just let them use the extra seats. I of course charged them a cancel fee and told them to request XL. I even had a guy once with 9 suitcases call X.... cancelled and told him to call XL. Some people are just so cheap but they end up paying XL AND a cancel fee in the end.
I have a 2008 Tahoe and can only do XL, no SELECT, no BLACK, no Airport. I just do X rides when im far away from the city to get back. Lesson learned.
That older lady honestly thought POOL is a bigger car to transport her stuff. I explained it to her, got $ 10 extra cash.
