I took the cab 170 from the hotel in Vegas to a business meeting in Henderson NV. I had my GPS going as well as the driver had it on his "smart phone". I was distracted on the phone with the bank so don't know either the driver missed the right turn or the "GPS took us a longer route" but we were now going not the most direct route. I showed him immediately on my phone that we were taking the EXTENDED ROUTE that a wrong turn had been taken & was adding an addition mile onto the trip. The young driver of cab 170 refused to credit me the unnecessary additional mileage & this made my bill higher due to either driver error or GPS error either way I didn't appreciate the lack of customer service. I still tipped 20% because I could & because another's wrong doesn't make it wrong/right for me & honestly he probably really needed the $.
The kicker my return route via another cab back to Vegas took me 11 miles & $10 cheaper. My trip out to Henderson was 9.5miles & 10$ more for less mileage driven.
