No ma'am, no. No.
If you insist on continuing to use the archaic, otherizing, and racially derogatory term "oriental" (which you really shouldn't anyway, because 1) It's 2015, and 2) Why?), it applies to products and inanimate objects, not people. Not. People!
Rugs can be oriental. The market that people often visit to buy goods produced in Asian countries can be called oriental. What is not "Oriental" is the grown woman, who happens to be one of the managers of the store, who also happens to be Asian, who is taking time out of her busy schedule looking for a single book for you, while your impatient behind has got all the other customer service people (myself included) on the same wild goose chase by asking them to find that same book because the manager (who would know where things are better than anyone else) apparently isn't moving fast enough for you. She already has it covered. And she, ma'am, is not "Oriental".
"Would you happen to know where this book is? The Oriental woman said she knew."
That word rolled off your tongue so slick, I almost thought you were trying to be funny. You have no idea how hard I was trying not to roll my eyes, screw my face up, and catch an attitude with you. Like seriously, What did you just say to me? That wasn't even directed toward me, and I'm mad about it.
I don't care if you're older and white. I don't care how you were raised. I don't care about "the times" or "the way things were back then". I don't care what you meant or didn't mean by it. I don't care if you didn't know any better, because if you cared at all about what people who don't look like you prefer to be called these days, you could've asked somebody or looked it up (read: educated yourself) by now. And I certainly don't care that you're a customer and we're service people, because bottom line is the store is our house. Just because you are a potentially paying guest does not mean you get to disrespect us or hold everyone up due to your impatient assumption that the person already trying to help you is clueless.
No ma'am, no. Just. No.
