If he's entering the bookstore, he might shoulder-check a tall gent in black, dark glasses hiding his eyes, carrying an armload of books with titles such as "The Golden Bough", "The Coming of the Faeries" by Arthur Conan Doyle, "The Varieties of Religious Experience" by William James, "The Book of Dreams and Ghosts" by Andrew Lang. One book, Arthur Waite's "Guide to the Tarot" drops from the top of the stack in the process, hitting the floor at their feet.

"Apology accepted," the other replies, with a polite mix of patience and mild irritation, as he starts to reach for the fallen volume. "I've had far worse days: at least this time, it's a fleeting nuisance from a quantifiable source." He'll tip head toward the stack of books as if to indicate there's a good reason for his rifling the occult section.
