Many shops offer Chai Kurdi (Kurdish tea) as a complimentary drink with good business from the local tea vendors in the bazaar. It is very popular prior to festivities such as Newroz (Kurdish New Year) in which business excels with larger crowds and customers.
In many shops, offering Chai Kurdi creates a welcoming atmosphere and attracts customers, especially during festivities like Newroz, when more people visit and shop.
