There is also ample opportunity to buy fruit and nuts from street vendors who literally spread their wares out on the street. The selection depends on the season. The customer may always taste these products before buying. It is cheaper to get these staples at a mill than at a market. Again, remember to bring a basket and plan to buy a month's supply.
Most people have only water, tea or occasionally coffee at their houses.
The beverages may or may not be cold depending on the vendor. If you have to purchase more new drinks than you have old bottles to trade, the additional bottles will cost more. Basically, you purchase the bottles and then continually exchange them.
