No offence intended, but my opinion is, the question of whether or not he punts should not even come up when you're looking for a partner. You are only focusing on that because you know that part of life well, having worked in it before. I mean, imagine if you never worked in this industry, surely this question wouldn't be so important right?
Your experience with that guy was just bad luck, in my opinion. You could've met the same guy without being a worker, and he would've done the same shitty thing.
