The agency I work for has its offices in a beautiful building designed by Gustave Eiffel. Yes, that Eiffel. It used to be a subsidiary building of the main Printemps department store.
The reason they can afford this beautifully designed building is due to some extremely clever economies internally.
For example, there are no kitchens. So clever! We wash our mugs in the bathroom sink. Right next to the toilet.
Which is lovely, but still, I've resigned.
