I like the fact that there are always reliable suppliers and fresh goods in the Subway. I don't like the fact that every year the assortment of goods is getting poorer and poorer, soon the Metro will turn into a large rural store. I don't like the lack of employees in the trading floor, in some departments the goods are endlessly shifted from place to place, and there is no one to ask where what lies.
A large supermarket with a huge assortment, with a huge parking lot. The disadvantages are a lousy toilet, a small number of locally produced goods, wild prices for vegetables, and a small number of simultaneously operating cash registers.
For the convenience of customers, they could put benches and coolers with water, but the Metro network is unlikely to do this...
