Where to email/contact regarding in-store retail experience?

Does anyone know how to contact Apple regarding the in-store retail experience? I’ve looked through Apple's website and support pages, but all the options focus on products, apps, or websites. There doesn’t seem to be any category/contact for addressing issues related to its physical stores. I suppose that absence also says something about how little emphasis the company places on the in-person retail experience...

If anyone has successfully contacted the company about a similar issue, I’d appreciate it if you could share how you did it. Thank you!
