Their is a reason for the oil as it is the tradition for anyone watching to place paper money on the oil that is on the body. When I was in Tonga, I was encouraged to get up and dance.....oh my gosh I did, not the Tongan dance or style !!!!!! but I was quite taken aback when people I had never met before came up and began sticking Tongan money anywhere they could !!!!! bit disconcerting for me, actually I collected quite a bit, maybe that could be a job I could consider........of course I handed it over to the family.
