Auction etiquette

Is there any sense of etiquette at auctions today? I've been to 6 auctions this month and all were so noisy it was hard to hear and get bids seen. People were milling all over including walking right in front of the auctioneer. I suppose the auctioneer is happy to have people coming to buy, but should it be a free for all? I know these are not high price events like Sotheby's but shouldn't people try to show some courtesy? TURN DOWN your cell ringer, don't bring your little pooch, don't walk in the way of the staff or auctioneers. End of my rant.
