Precocious shopper overheard

"And what are you buying," the store clerk said to the three-year-old girl whose mother had just paid cash for a couple of items.
    "I'm buying a bracelet," the girl said, flawlessly.
    "And how will you be paying for that?"
    "My charger count."
    The girl's mother laughed. "Now, honey, you know you don't have a 'charger count.'"
    "But, Mommie, you know we have your ready-card."
