Last company where I faced external suppliers, I had to take a training where they said we couldn't accept any item worth more than like $20, except food or alcohol during a presentation. But we could accept such items on behalf of the company, and they would be raffled off to a random employee. One time a guy in purchasing got a giant brass horse head from a Chinese supplier. I guess nobody signed up for the raffle, so it became a permanent fixture in the cafeteria.
