"A fat chance we'd have of collecting the guarantee if we were chopped into mincemeat," Red-tie interrupted, shuddering slightly as the implication of his own words hit him.

Anson felt a moment of panic as he failed to remember an applicable rule from the Salesman's Guide, but it formed in his mind at the last moment: Rule 18: Never argue with a customer—change the subject.

"Why don't you come with me to the Green Room?" he asked. "The very latest models are on display." He walked slowly at first, then more quickly as the couple allowed themselves to be led. He slid his hand near a hidden switch in the archway, and floodlights came on just as they entered.

The woman uttered a little squeal of delight at the sight of a very handsome figure dressed in a cutaway, standing in an attitude of service.

"Oh!" she breathed dreamily. "He would make such a wonderful butler."

"Well, wind him up and let's see what he'll do," growled the man, his face florid in the colored light of the Green Room.

"I'm so very sorry," Anson said, slightly flustered, remembering that this was always the crucial moment in a sale. "The Roboid cannot be activated for demonstration purposes."

"What?" roared Red-tie, incredulously. "Do you mean to say you want me to buy the damned thing without knowing whether it ticks or not?"

Anson tried desperately to remember the best rule for such an answer, but failed. He plunged desperately into his own explanation.

"You see, our Roboids are matched to your family personality at the time of purchase, and activated then. We cannot erase a personality once it has been transferred to their sensitive minds." He saw the disbelieving smirk on the man's mouth and felt that the sale was indeed lost. But he plunged on, desperately.
