There are a lot of etiquette sources on line and seminars offered all over the country.
I googled "business etiquette" for you, it is a more masculine angle and you won't have to suffer through weddings and setting tables. (Of course, it is nice to know where the shrimp fork goes!)
Go to your local library or book store and kick back with Emily Post Book of Etiquette and read through your areas of interest. Post has been publishing since the '20's and has updated to our times. It covers many topics that you'd find interesting.
Your local bookstore probably has 3 or 4 shelves of etiquette books geared for all different topics. Don't buy the books, sit and read through them, who knows there may be a cute little chickie checking to see where the shrimp for should be placed!
Good Luck
