hamacas

Everytime I´m in or near the plaza, I get asked at least 3 times if I want to by a hammock. `Hamacas! hamacas? hamacas!` The more it happens, the funnier it´s becoming. I think I should be annoyed, but instead I think it´s really comical. Yes, I´m a gringa, and no I don´t need a hamoca, thanks!
