The seller refused to sale fresh fruit. First he told me to buy older ones. Is that legal?

At least once, many customers faced a akin situation. In the store you can see fresh, rich fruits, but the seller refuses to sale them and offers older goods, frequently at the same price. It turns out that specified practices may have legal consequences.
