I usually change it in Al Ansari. This time I decided to change $ 500 here, since the office was on the way. At the 3.6 rate, he counted 1,700 dirhams. To my question, why not 1.800, he said that they had a "commission". I laughed and told him to cancel. After these words, the "commission" decreased from 100 dirhams to 10 dirhams)) be careful and change it better in online exchangers.
