I have booked a service to take me from the Philadelphia airport to Ambler, Pennsylvania. The reservation I made says no tip required, because the tip was included in the price. My plane arrives at 11:00 p.m., which means the driver will be making a late night run. Do I tip him anyway, and if so, how much?
If the tip is included, you have no obligation to tip additionally, and limo drivers are certainly accustomed to picking up passengers at all hours. That being said, if you find the driver to be particularly courteous/friendly/ helpful, I would add another 5-percent to the overall amount.
