Whether they're pouring coffee or importing it, people deserve respect, and behaving like a boor is bad business to boot. Times have changed.
Business is no longer the exclusive domain of white males.
And however that may or may not affect you personally, as a small business manager, a healthy dose of tolerance is wise. Small companies don't have trained PC crews to apply an outer coat of open-mindedness. Chances are, you're the only image maker you've got. You can't possibly keep pace with politics. Do treat everyone with dignity.
