Sounds like he's pretty reactive ( in his own way ) to mention the obvious.
Petsmart, could at times be a great place to proof a dog.
I'm kind of stuck on the "fault " thing myself currently with my gal...closing in on 2 years. But, I do know this...regardless of another dog or whatever element might cross your path...such as this dude ( guy ) that crossed Dude and your paths...your goal I am certain is that you will have full control of Dude and be a kickass team regardless of the "scenery".
