Draco had been especially captivated by the packets of peppermint chewing gum. He opened one as they browsed the aisles; to Hermione's horror he tipped the entire packet of gum into his mouth at once and tried to chew and swallow the large lump that formed. She made him spit the ball into her hand like a child and waved her wand through her pocket to vanish the ball then showed him how he was supposed to eat gum. Draco didn't think he would ever find himself without this muggle "gum’ again. He grabbed every packet from the shelf and dumped it into the trolley regardless of Hermione's perpetual frown.
