as a young person who hates cigarettes and recently went to las vegas for the first time, it was wild walking around the casinos thinking "this is what everywhere used to smell like, its incredibly disgusting!" I'm glad we managed to stop smoking indoors, probably one of the greatest advances of society.
There’s an enclosed area in the Las Vegas airport where people can smoke while using the slot machines. If you ever find yourself here and are curious what it’s like to live with parents who chain smoke, visit this awful little piece of hell and you will satisfy that curiosity.
I went to a casino for my 21st birthday and the stench of cigarettes in the non-smoking section was enough for me to never want to return. That and it was almost entirely penny slots and I got bored of those as soon as the novelty of actually gambling wore off
