Other merchants are not so navigational, and maybe go to two close-by markets. Many other sellers are just local people, who have just enough wherewithal and wares to sell in their local suq once a week, or perhaps only a few times a year. A suq, even a small country suq like Asni's, has an entertainment component. People come from miles around and share the news. Musicians play for a few pennies.
People take time to congregate, spend some money, and maybe make some money too.
