Unfortunately, a craps table is usually full of superstitious people. If you do or say something against their silly beliefs, they sometimes give you dirty looks or verbally abuse you. To help avoid embarrassment, ridicule, and possible vocal confrontations with these people, learn their superstitions and practice craps etiquette. I know it's foolish to play along with people's crazy superstitions, but you'll have much more fun at the table if you do.
Practicing good etiquette includes not forgetting to be nice to the dealers. Don't annoy them by throwing chips at them, knocking over their chip stacks, or blaming them for your losses. If you tee off the dealers, how can you maximize your fun? Besides, it just isn't nice. Your friendly attitude will be infectious, soon making the whole table more fun. (Sounds like a good time for group hug and round of Kumbaya.)
Regardless of what so-called "dice doctors" and "craps kings" write on their websites, there's no such thing as a "sane" craps superstition. One superstition isn't more or less sound than another. They're all the same--silly. But you must heed them or the idiots at the table who actually believe in them can make your time at the table miserable.
Respecting many of the idiots' superstitions has matured into traditional protocol at the craps table. Therefore, you must know and understand them. In my book, The Secret to Craps: The Right Way to Play, I discuss about 30 of the most common craps superstitions and elements of etiquette.
