In one part of this building ladies sold from large buckets of cream and big blocks of butter. In another part meat was sold on the counter, while the butcher chopped up the animal behind. Car parts can be bought in stores, but people look for better deals at the open automotive market. From what I saw, most Russians do their own repairs. Also, checks and credit cards are virtually non-existant in this part of Russia, so everyone deals in cash, sometimes shopping bags full of cash.
People build the dachas themselves.
Dachas are usually empty during the winter, but kids on vacation and retirees often spend the entire summer there. Russians know their mushrooms and berries. One of these guys is an electrical engineer, and the other is an economist. Like a lot of folks, they've just spent three days in the forest collecting berries to make preserves. Other people sell the berries they collect at the market.
