Uneffective way of detecting fake currency notes

Wanjala was a  great grocer in a busy market. He had heard that some people were using counterfeit notes to bury goods in the market. He had observed other traders holding the notes against the light and look through them. When he inquired notes. Henceforth, he started the habit of holding every none up against light though he did not know what to look for. One day a customer saw Wanjala holding a note against light. "What are you checking 7" the customer asked curiously. "If the customer doesn't take off, when I know the note is not fake!"
