Yeah, I have difficulty walking through department stores too, but that just means (as I hinted) that I'm prone to falling into the fallacy that if it's not causing me problems it won't cause anyone problems. (I know for certain fact that this is untrue, because while lots of my hayfever triggers - lilies, in particular - are very common, I'm absolutely fine with roses but I spend non-trivial amounts of time hanging out with someone who gets migraines if exposed to rose scent, so I have to make sure I don't wear roses around her!)
