Tips are discretion of customer and states it on the agreement I received from Carmel. After the driver picked our party up and was in route to the airport, he said it was 21$ tip that had to be paid. Well, he had us where he wanted us because we could not make arrangements fast enough to get to the airport. I will Never use them again. I decide the amount of tip that I give and usually is 20% for good service not 30%.
