2. In the case of real interest, you should learn about the contents of the session, visit the exhibition in advance and take the information about the lots in advance.
3.Dress according to the environment, time and public event.
4. Punctuality is the basic rule of any social event. Those arriving late may lose the opportunities.
5.Sign up before the session if you want to do bid on any piece or wish to receive calls at home later.
6. Avoid alcohol, especially if you want to do some shopping! In many auctions drinks are offered, but sobriety is advisable to good business.
7. By placing a bid, make it clear to the auctioneer; try to be discreet to the public and visible to the auctioneer.
