Don't know that I would have told him I "didn't need his advice". I try to always take advice, good and bad, and then decide for myself the merit of the offering. But you run a risk of cutting off a relationship that you may need someday.

Try to discuss the "picture" that was presented by this knucklehead's actions and have him discuss the potential positives and negatives of such a situation. Hopefully, he'll see the negatives far outweighed any potential positives and can offer a "better way" of handling future encounters - he definitely compromised everyone involved and "nothing good" could be expected to come of that.

You did the right thing by drawing a firm line with his behavior; but, look for more of a "win-win" situation in the future where everyone involved can feel and want to continue to be involved - you never know when or if you'll need this guy in the future not to mention the positives you're demonstrating that "invites" cooperation and teamwork.
