|But I already have money!|
Janelle Jones first noticed the mistake—which is just so typical—when she was driving home and saw there was no food in her bag, just a couple bank deposit bags and a $100 bill.
And no, Jones didn't try to keep the money. From the Associated Press:
[Husband] Matthew Jones says the couple briefly considered keeping the money, which they certainly could have used. But he says he and his wife are Jehovah's Witnesses, and that "Jehovah sees everything."
After she returned the cash, the store's manager offered Jones five free meals, which, with her luck, will probably all be stupid diamonds or gold bullion or something.
