If you look closely above you’ll see the talisman of the evil eye. The eye is said to ward off jealousy, envy and misfortune that other people may bestow on the owner.

Small cafe owners, clothing shops, butchers, and large corporate entities alike display the talisman just in case the the folklore is true.
