Excellent advise by all. Having been on both sides of the table, my pet peeve is the children whose parents haven't taught them any manners. LOOK, DON'T TOUCH, and you may ask questions, just don't interrupt. I started attending shows when I was 11 and those rules were clearly defined for me. I found many table owners who were more than willing to answer a young mans questions and started some life long friendships.

I have a secondary question concerning shop etiquette. In the late 70's I was in a shop in Brunswick, Maine where I did considerable business. An elderly couple came in with a 22 rifle an a Marlin model 90 O/U (218 Bee & .410 or 20 IIRC). I wanted the Marlin. I stood patiently by as the owner made his deal with the couple and after they had left, asked the owner what would he take for the Marlin. His response was that he gave someone in Mass. first dibs on those. Now I was prepared to give him a reasonable instant profit, but it irked me that he wouldn't even offer it for a price. As a result, for the next three years I was there, I never did business there again nor recommended him to friends. I could have just as easily started a bidding war (not that I would have) but let him buy it at a very cheap price. If you were buying and selling, would you take his position or would you name a reasonable price and offer it up?
