A long time ago, in the first half of the 90s, there was such a story in one large regional center.
16-story "tower" type, elite housing of Soviet times. Some company bought the whole first floor, and decided to equip there a salon for the sale of something big, cars, it seems. And to do this, remove all the external walls, putting large glass windows on them, and all the internal walls.
Fortunately, someone in time, at the very beginning of the "handicapped" works in the executive committee. And although the times were of great pofigism, but even the employees of the executive committee were impressed with the consequences, or if someone lived there in this house, but, in general, stopped all this matter.
And the owners of the firm even in the newspaper then gave outraged interviews: here, say, bureaucrats, such a business idea was rooted!
