Why cosmetics stores in 1 floor

As ms often go shopping or often 'by' men go shopping, I think it is not difficult to find that the mall looks like: rarely more than 5 layers; 1 / f, cosmetics, jewelry, often do not set the bathroom; The cinemas usually at the top; Restaurant may be in 1 floor underground or top. There are very few on the 2 3 floor sell children's products. You mean that these arrangements are optional? That you can do as a head of bump into the spider's web of small moths naive. Mall in geography, actually hiding sinister secret business. The most expensive, are on the first floor why malls are so long?
