A can of Mountain Dew rolled and thunked into the cash machine.
The cashier waved it in front of a scanner which pinged.
Picking the can, the cashier went to end of her table and rolled it towards the scanner again.
In a closed grocer's shop.
Everyone else was gone.
I was talking to @vivekisms and he told me about a 55 word story challenge with theme "At The Grocer's". So, I wrote what you read above.
That's about it.
