I never buy anything of anyone who try to push it on to me, especially touts (dressed as sharks)

I once walked to the bottom of the front steps leading to my hotel entrance in Ho Chi Minh City to have a smoke and this moto-taxi guy tried to harass me into using his taxi, I kept saying no and he got quite agitated and ended up yelling at me wanting to know why I would not use his service. I said to him "I'm not going anywhere, just came down here to have a smoke". Should have seen the look on his face.
I judge places I have been to by how bad hawkers and beggars annoy you. Sapa in Vietnam was bad, as was Nha Trang. Visiting the Taj Mahal was a highlight of my travels but the beggars were very forceful and determined.

And I too want to see a pic of the shark lady.
