Allergies are common. For me it's long haired Cats and a couple of Perfumes. No big deal, if my throat swells up, I move or go for a walk outside. Why make a big deal about it or even say anything?
We had a couple of kooky sisters who made a BIG deal about it in a couple of halls we were in. Insulting people, stomping around, wearing masks, refusing to sit in the back room with the air cleaner we bought for them. Insisting EVERYONE buy special no-scent hygene products. Yet... I would run into them in smelly paint and cleaning departments at the local Home Depot and they cleaned homes for a living. Selective allergies I guess.
In the old days I never heard of so many of these problems.....untill Watchtower created the regional building commitee $$$ and INSISTED we remodel by covering up the Kingdom Hall Windows, installing their new GLUE down carpet, their new seats, and their new garish vinyal wall covering, and cheap commercial lights. Suddenly everyone stated feeling nauseous during boring meetings for months as the high mark-up RBC materials off-gassed manufacturing solvents.
