I've been thinking about your meeting. Remember, they need proof that you have sold these cigarettes. Heresay isn't proof. I would also seek some sort of representation beforehand. Are you a union employee? Do you have a union rep? And above all, admit to nothing. They may try to be friendly with you to try and get you to slip; this happened (not to me) when I was interviewing for a US Customs job and needed security clearance. One of the gov't interviewers asked an interviewee something like, "Surely, you smoked a joint sometime, right?" The interviewee answer yes and didn't get the job. Good luck.
