If you want to understand better the culture and the Yemeni mentality, you must know something about Qat (Catha Edulis). It is a legal drug in Yemen, which has a stimulant effect. It is an important part in the economy of the country . After lunch time, the country slows down, and the Yemenis re-join to chewing Qat, doing of it a forms of social relation. Any corner can be an unexpected market. Up to you to accept an invitation!!!
