Recently, I've seen a few people doing this, and it surprised me (and when did so many people switch to roll-ups?).
I don't want to see people fiddling about with tobacco pouches and cigarette papers in coffee shops and restaurants. Obviously, if they could smoke them there then it makes sense, but now it seems to me like going into a cafe and starting to make your own sandwich (with no intention of eating it in there obviously).
AIBU? A friend says I am, because if they did it outside "their tobacco might blow away", which while possibly true, hardly seems a good justification to me.
