GOOD ONES!

Bar code?   LAW

What chambers of commerce do...    COURTBUSINESS [theme answer]

Not being one, I have only a vicarious knowledge of the term "hunk."  I believe it means a physically attractive male, not GOB (for "good ol' boy"), which has nothing to do with appearance.  GOB is also an abbreviation while hunk is not.

GOB is a word beyond being an abbreviation, and it is this sense it is employed in this puzzle:

    * Main Entry: 1gob
    * Pronunciation: \ˈg

[magus]

Thanks for cluing me in.  I should have thought of it: hunk means "a great deal" as does gob(s).
