In very vast territories of Western Europe, coldtea, direct providers such as restaurateurs still work through reputation. You'd stop working if the clientele saw you are not trustworthy. Edit: What you will see in the frontpage of the "Truffle Dogs University" in Roddi - http://www.universitadeicanidatartufo.it/prodotti.htm http://www.universitadeicanidatartufo.it/prodotti.htm - is relevant: you will see the picture of a guy in front of the products. He "puts his face on it" - that is his reputation at implicit stake -, and he is proud. That is the normal standard. Also notice one important thing: «Available for /small/ shipments» - the goods are in limited quantity (fake ones could be produced ad libitum).
