Tomorrow, I will finish up a 2 day/2 night trip with my driver to/from Dehli/Agra. As a solo female traveler, I must say that Magansing (hopefully spelled correctly) from Namaste India has been the perfect help and has made this a comfortable happy experience.
What is a customary tip in this situation? My hotel service book suggests 10% is a typical figure for tips. I'm getting low on rupees, too; would it be ok to tip in US dollars?
