So as a taxi driver with asthma and horrific allergies, I've found dog owners are not typically terribly understanding when I tell them we're going to have another cab come pick them up. I've had several people insist that their animal is a service dog as if this somehow changes my own health condition.
I've often found that my own access to public spaces is limited by the use of service animals and straight up pets in public places. I don't even try to go to breweries anymore. I wouldn't bother trying to get on a plane. Even hotels are basically a no go for me unless i want to get sick more often than not.
I don't pretend to have a solution to this, but access to public spaces for animals and for some allergy sufferers is mutually exclusive. It makes it a lot more complicated than 'service animals should be everywhere' or 'allergy sufferers should have access to public spaces'. The two are kind of in conflict. It sucks.
Nobody pays any mind to air quality and it's made my life a whole lot more difficult than it needs to be.
Anyway, i feel for her, but i think the service animal stuff is way over simplified and people forget that other people with disabilities also pay a cost.
