I'm so thankful that most, if not all airports in China and SE Asia have well ventilated smoking rooms that cause no harm or inconvenience to non-smokers. I already have them mapped out before landing after 14+ hours in the air before boarding the final leg to Bangkok. Hopefully Thailand reinstates them as well!! Most of us smokers would love to be able to quit. Some can & some can't but we are all paying customers and human beings. Addiction or not.
