Rita took her new vacuum cleaner back to the shop with a twenty-pound note taped to the handle.
The assistant, Joel, looked at the note.
“Is that a refund request?”
“No. It’s part of the demonstration.”
“What’s wrong with the vacuum?”
“Nothing. It works beautifully.”
Joel waited. Rita waited too. Finally he asked whether she would like to exchange it for one that didn’t.
Rita explained that her husband, Len, had recently retired. He was determined to help around the house, but every job became a technical investigation. Washing up required a comparison of detergents. Hanging a picture required the recovery of three old spirit levels. Vacuuming, apparently, required a new vacuum.
“He said the old one had lost suction,” Rita said.
“Had it?”
“It picked up everything except him.”
She had bought this model because it was light, quiet, and simple. Len had read the booklet twice. Then he’d watched a video. Then he’d announced they needed a better test than “it looks clean.”
Joel nodded cautiously. “A measured performance test?”
“Exactly. I put a twenty-pound note under the edge of the rug and asked him to vacuum the sitting room.”
“That could block the hose.”
“It didn’t. He found it before switching on.”
Len had brought the note to Rita. She’d told him to keep it as a reward for helping. The next day he vacuumed again. And the next.
“Sounds successful,” Joel said.
“It was. Then he asked which room I was testing next.”
On Wednesday he had even vacuumed the stairs without being asked. Rita was so pleased that she praised his technique. Len said technique was important, but consistency was the real test. He wanted to know whether she’d varied the placement of the test note. She said she had. He nodded, fetched the narrow nozzle, and moved an armchair she hadn’t seen behind since Christmas.
Rita tried the bedroom. Len moved the bed, cleaned behind the wardrobe, and discovered twelve pence, an old watch, and a birthday card from 1998. He declared the watch a bonus and the twelve pence disappointing.
By Thursday, the house was spotless and Len was checking under cushions before breakfast. By Friday, he had asked whether she intended to conduct regular quality assurance.
“Still not the vacuum’s fault,” Joel said.
“I know. Let me finish.”
Rita had stopped putting money under things. Len vacuumed twice more, found nothing, and spent Saturday inspecting the machine. He emptied the dust container onto newspaper. He examined the filter under a lamp. He called the manufacturer’s helpline to ask whether the machine could lose objects selectively.
The person on the helpline told him not to vacuum currency.
“He said he wasn’t trying to,” Rita explained. “He was trying to recover missing test material.”
Joel covered his mouth with one hand.
“Yesterday he said this vacuum had become unreliable.”
“So you want me to show him it still works?”
“Please. Otherwise he’ll buy another one, and I’ll have to finance that as well.”
Joel plugged it in. He scattered a few crumbs on the demonstration carpet. The vacuum collected them immediately.
Rita nodded. “Could you write that down?”
He printed a service note: Machine tested. No fault found.
At that moment, Len entered carrying the parking ticket. He read the note and looked pleased.
“Good,” he said. “I told you we should have it checked. Did they find the twenty pounds?”
Rita peeled the note from the handle.
Joel asked, “Shall I show you how to use the attachments?”
Len brightened.
Rita shook her head.
“He knows how,” she said. “Show me the payroll settings.”
