As noticed by Alizés, a female member of our forums, Apple has made a blunder with women with the Apple Store.
In addition to the staircase, all the mezzanine is out of glass and this is likely to transform the shop of Apple in a meeting place for the Parisian Peeping Toms. Thus dear women, think a bit before going there to do shopping. Unless you want to be a star or to be the object of some jokes, wear trousers!
