I live in the Midwest and we have one in a strip mall. It’s basically like a mobile carrier store (AT&T, T-Mobile, etc). A few backless benches, a few service desks, a “sleek” counter, walls and large TVs lined with advertisements as well as some products (Xfinity/Comcast does mobile phone plans now too so they have phones, smart watches, etc for display). You can also return your equipment there but it’s mostly for signing up for services and billing help I suppose.
