Customs of the Country
Moroccans are known to be polite, friendly, and curious about visitors to their country. However, Morocco is a very hierarchical society, so people are dealt with according to their position in the hierarchy, not the order in which they happen to arrive. In markets this phenomenon is modified: someone selling vegetables will deal with several customers at once, so don't wait meekly to be served in turn. Be aware locals do not always say what they mean: what they say can be governed by the desire to please or, in the case of less charitable characters, the perception of what will work to their advantage. You don't need to take all these guidelines into account for simple transactions like buying train tickets, but they'll help in more complicated situations.
