I met him in August last year and he helped us out in the pouring rain and didn't want to be paid (although we did, double)because he said we hire him for longer trip later.
Later has come and I have lost his card :-(
I think his name is Putu and his stand is outside the Ibah Luxury Villas at the Campuan end of Ubud, next to the Ubud clinic and just across from, but towards, Ubud central from Murni's Warung.
If anyone knows this driver's name and details I would be very grateful as I need him later this month.
Cheers,
David
