I agree, it could be other elements in the store that affected you. At the LQS I go to one of the employees brings her very large dog (who is very docile) to the shop when she works. I am very allergic to animals of any kind and even if I am in another part of the shop, I always know when she comes in with her dog. My throat starts to itch something fierce. I have mentioned this to the manager of the shop but so far the dog is still brought in. The employee puts the dog behind the counter while I am there but that doesn't help if he is allowed to roam the shop while I am not there!!! Duh!
