No it doesn’t make you disappear, it can give you a false sense of bravado though. He may have got a number of another local punter in the bar. He may have met a dodgy dealer. The dealer may have asked him to come alone as to not draw attention. If meeting a dealer, it’s highly unlikely that they would want to meet directly outside the bar. This is all my opinion and speculation, I just wouldn’t rule it out. As mentioned by another poster, it’s not as taboo these days.
I’ve read other comments on other forums that he may have made it back to his home town and something happened there? What are thoughts on this?
