The sale of the shovel

Surely the shovel hadn't been shortened,
the shopkeeper shifted to the side.
The shovel shimmered newness,
the sharpest shovel in the shed, he said.
Still she was shill-shally on the subject.
The shopkeeper shifted his shilling
to secure the sale of the short shovel.
Shrewdly he began a shuffle with the shovel,
shimmying this way and that, shocking.
Still she smiled at the short shovel,
the shopkeeper made the sale.
