I am living here since 3 years, and I can say that it happened to me to be approached by local guys, but when I replied to them that I am not interested they left me alone. Thing which I cannot say about other nationalities from here, as Sudanese, Indians, Sri Lankans, in general labours. With these guys, I had to reply in a very aggresive way to get read of them...they are the dangerous people in this country! :(
