It really sucked when people could smoke anywhere. I remember so many times when I was at a restaurant just starting into a nice meal and suddenly all I could smell or taste was cigarette (or cigar) smoke. It was gross.

I also remember when airlines had a smoking section, which was usually the back several rows. I remember asking for a seat in the non-smoking section, and the one I got was one row in front of the smoking section; there was probably more smoke there than in the last row of the smoking section.
