I hate cigar smokers not because of the smoke, but the bullshit. In my world it is always just me sitting on a bench.
I understand the gathered around a doorway thing, but outside in a park? Doubt there's really a dense "fog of smoke."
As I was lighting up at the entrance to the park (before I saw the signs) some kid came around the corner of a statue and stopped dead in his tracks staring at me with his eyes wide. He then slowly backed up until he joined his parents then walked on the other side of them as far away from me as he could.
I felt like Joseph Merrick.
