There are certain areas on the beach that when walking as a woman alone or with another woman the hustlers stand in your way as you go by. Normally not an issue to just reply politely that what they are offering is not of interest. One guy kind of got to me, when he said "what's the matter, you don't like chocolate!" My mind drew a blank but I thought of a number of replies afterwards. Sometimes though, it's just not worthy of one.
