In Black Like Me, John Howard Griffin, a white man, describes what he experienced in his travels through the south in 1959 after he dyed his skin black. One Saturday he needed to cash traveler's checks, but the banks were closed; so he asked stores to cash them or at least let him buy something. He writes,

"They would have cashed a traveler's check without hesitation for a white man. Each time they refused me, they implied clearly that I had probably come by these checks dishonestly, and they wanted nothing to do with them or me. 
"Finally, after I gave up hope and decided I must remain in New Orleans without funds until the banks opened on Monday, I walked toward town. Small gold-lettering on the window of a store caught my attention: CATHOLIC BOOK STORE. Knowing the Catholic stand on racism, I wondered if this shop might cash a Negro's check. With some hesitation, I opened the door and entered. I was prepared to be disappointed.
            "Would you cash a twenty-dollar traveler's check for me?' I asked the proprietress.
             "Of course," she said without hesitation, as though nothing could be more natural. She did not even study me.
I was so grateful I bought a number of paperback books--works of Maritain, Aquinas and Christopher Dawson."

John Howard Griffin's "proprietress" was our founder, Florence Henderson.
