…You are aware of how both allergies and air quality works, right? Also, most shows even in art houses don’t include scent effects of any kind, hence the warning. If it were common, the warning would likely be unnecessary.
But lovely of you to claim I am the oversensitive one, as apparently adding a single word to an already existing warning, one that could literally save someone’s life by preventing a physical ailment, is too much for you to handle reading!
Fair, but people have sensitivity and allergy to different things. Adding it to an existing list of potential deal breakers for those who would rather not risk their health is a case of cost/benefit: it costs nothing and benefits many.
