Americans, Germans, Canadians, Martians... whatever. The beach vendors are equally annoying to all vacationers and surely must hurt your return visitor rate. I didn't intend to single out Americans.

They wouldn't bother me if they would leave someone alone who obviously doesn't want to be bothered. Waking people up sleeping in a beach chair to try to sell them something is crossing the line. Demanding "respect," wanting to do that silly fist bump thing and chasing after me to ask me what I need when I have already politely said NO and kept walking is crossing the line.
