Heck, even before you take into account differing xenobiologies, this has precedent on earth; different cultures are often unused to how other cultures smell.
I’m sensitive to smells and perfumes so any culture that uses them often is difficult for me. Hey are there scent suppressants I can buy or is that future tech?
There would so be a market for it, although I’d rather have the artificial odor market be killed off instead. Saves a lot of waste as well. (as the air pollution, those smells… yuck)
Hey I’m a condo maintenance guy! I swear Snelling garbage and bad smells all day has destroyed my sense of smell. If someone’s wearing strong perfume it bothers me, but I can’t smell bad smells or notice them
I’ve heard that white people smell like bologna. Could never stand the stuff myself, but I can’t vouch for my scent! Tangentially, I think my dogs’ paws smell like salami. “Ol’ salami paws”, I’ve been known to call them.
