At first I thought that I had entered a 1950s set. Two walls are a dull pale blue; one is a dull pale yellow. They have an institutional feel and look like they should be in an old downtown office building. I found the color combination off-putting at first, as it gave me a queasy feeling. But I got used to it. Bright orange spherical drop lights hang from the ceiling. I'm not 100% sure because this isn't my design period, but it really does feel very 1950s.
And just as in those detective movies from the '50s, a metal ceiling fan whirs away. There are even slatted blinds -- on the small windows above the large storefront ones. A mini-library is set up in one of the storefront windows.
Thankfully, although the staffer working behind the counter continued the '50s theme, she was cheery. She wears a dress that looks like it could break into song on its own.
