Moroccan culture has several aspects that visitors need to get accustomed to, including greeting with kissing or hugging friends of the same sex, eating with hands from communal bowls without utensils, and being stared at out of curiosity rather than unfriendliness. Punctuality is more flexible, conservative dress is expected, and bargaining is an essential part of shopping. The medinas have narrow streets crowded with donkeys transporting goods, and central squares like Djemaa el-Fna feature lively food and performances.
