Open-air, public markets have existed for as long as peoples have engaged in trade. On the daily, the market serves as a place to pick up necessities, grab some lunch, or haggle over how much it would be to get that stain out of your shirt. Markets held on holidays, focus on livestock and agricultural produce. Whatever your business, the centrally located money changers are eager to assist brokering deals or handling large sums for large purchases... at a modest fee of course.
