From affordable Kirkland items to bulk offers on name brands, there’s a lot to love about Costco, but best of all might be the free samples. Free samples are a great way to get customers to try and buy new foods, but if you’re the type who gets a little hungry while browsing the aisles of Costco, here’s how to go back for seconds.

At Costco, there’s no policy that limits the number of samples a person can take, so Costco sample servers don’t care if you take more than one as long as you are polite to the servers and considerate of those around you. However, if you indulge yourself too much you might end up as the subject of a Reddit thread.

On Reddit, one former Costco sample server shared their most extreme customer experience in which one guest cleared nine trays of Ferrero Rocher hazelnut chocolates — a total of 63 chocolates — before walking off. Considering that Costco sells a 48-pack of the treats for $17.99, that customer consumed almost $24 worth of chocolates.
