MILWAUKEE, WI — Recent security camera footage of Martha Holmes shows that the 73-year-old Wisconsin native ignorantly attempted to use cash to pay for her groceries yesterday.

The video clearly shows Holmes offering a $20 bill to a confused store clerk, even after he gestured for Holmes to swipe or tap her credit card or iPhone to pay.

"I was so confused," Holmes told reporters afterward. "The nice man kept asking me if I had a chip or not, and I only ever buy chips when the grandkids come over for a weekend. And then he said to tap my card, but I don't have a card. Do you think he was talking about those debit cards my son keeps mentioning? I hope he didn't think that I was trying to pass off a counterfeit bill or anything."

The video also reveals that Holmes fished a coin purse out of her real purse at one point in a desperate attempt to give exact change. Though the footage is somewhat grainy, it appears to record a violent allergic reaction from the cashier.

At publishing time, Holmes had been seen writing a letter to the grocery store to ask if they would please start taking cash again.
