Yeah, sometimes it bothers me. Several months ago I was eating at a restaurant in the bar area. There was this older woman sitting several tables away, she was smoking heavily and drinking. Something choked her up and she started coughing constantly. It was so bad that she would gag and then continue coughing. Then it died down and she lit up again and continued drinking. When she had another attack I had to leave. Got right up, told my friends I was leaving and got out of there as fast as I could. I kept feeling like I was going to gag too. It took awhile to calm down, but luckily I didn't have an attack.
