I've never been to Morocco, but I have experience haggling with Moroccans. In recent years, there aren't as many as there used to be, but before, there were many Moroccan street vendors in Portugal. I loved haggling with them because they would always start with an extremely high price and end up selling for less than a tenth of that. They probably still made a good profit, haha.
