Akpors and the woman’s purse

Akpors returned a missing purse to the owner in a market.

The lady was so grateful but when she looked inside, she got confused and said, “but I had just a single note of one thousand naira, now there are ten notes of one hundred naira, how come?”

The boy said, “na me change am, because the last time I help person find purse she say she for give me something but say change no dey”
One word for this guy?
