Why I Won’t Go To A Hookah Lounge Anymore

So the other day I had a very relaxing night time hookah session at home.  As I was smoking, the smoke started to get harsh so I did what any hookah smoker would, purge.  What purging does to a hookah is when the smoke or vapor gets a bit harsh, what you should do is take your hose and blow through it, which will make all of the smoke/vapor in the glass base and the hookah stem go out through the purge valve.  This usually cures it.  But when I went to purge during this hookah session, I looked at my hose and it made me think.
