My stay in Luang Prabang has been very nice and I have met some extraordinary local people who are kind and helpful. That be said, I have twice been ripped off by boat operators who would not give me change for the fee that they quoted to me. Granted that it was only a few dollars but it is the principal of the thing! I always tip and am generous when I receive good service but my experience with the trip operator on the Namkhan River to go the short distance to the Tad Sae Waterfall has me outraged. I made a huge stink and received some of my change but not all. Needless to say I warned other arriving groups of the treatment, gave away my ticket and left! My question is this, has anyone else experienced this sort of rip off while here?
