A man comes to a store or travel agency. He gets a working vacuum cleaner or an exciting trip - and is happy. This is an ideal situation, but in reality expectations are violated.
The buyer returns a defective vacuum cleaner, but the administrator does not accept it. He was poisoned by expired yogurt and writes to Rospotrebnadzor - but does not know the name of the company. The pharmacy looks dubious - and he can't check the license. To protect consumer rights and help resolve disputes, the state obliges entrepreneurs.
