could be any two cities in the world really...private transfer in his car...no company involved other than maybe the concierge at hotel or riad got him for you. You agree on the price. Is a tip expected over that price? I don't want to seem cheap or have him think that service was not good but my thinking has always been he is getting 100% of the money and I assume he is quoting what he thinks is a good price with enough profit after expenses. I know it is different if the driver is working for someone else. Any thoughts on this situation? Thanks.
