Well, it depends on how the wishing mechanism works, if it's a lawyer genie, a monkey's paw, or something kooky. Really, there's so many factors at play, like if the shop is made out of bricks and mortar or just sheer magic powerz, if Aya was able to control her wish consciously or not, if being aware that a wish is happening counts as a wish affecting or applying to you, etc. The thing is, the one person who would most like to argue all of the sides of this would be Aya herself, so i think we'll probably cross that bridge when we come to it. My intention with writing that wish was to show that Aya's the kind of person who really does scroll all the way to the bottom before clicking "Agree" and loves finding loopholes in these things.
