Joanna Lumley, 78, shared a humorous supermarket encounter where she lightly held two women by the neck while encouraging them to buy cotton candy grapes instead of regular white grapes. Passionate about the sweeter variety, she insisted they try them at least once. Later, she saw the women again, who told her she had "changed their lives." The Absolutely Fabulous star's playful persuasion highlights her enthusiasm for the unique, candy-floss-flavored grapes, which are a pricier but flavorful alternative to standard seedless green grapes.
