It never really bothered me, maybe when you are around it often enough you become immune to it
I am one of those who kind of liked it. It sticks with you, that's for sure...I could smell it while I was reading your post! haha! You can't be the only one who does not like it and it could have been a combination of feeling uncomfortable and the more you notice something, the more it tends to irritate...does that make sense? Probably could not wait to get out of there as it was and then add to it the incense...then the headache...yep, I can see it
You are surely not alone!
