From the latest by William Gibson:
"That's where you come in," he said
"I do not."
He smiled. He had, as ever, a great many very white teeth.
"You have bacon in your teeth," she said, although he didn't.
Covering his mouth with the white linen napkin, he tried to find the nonexistent bacon shard. Lowering it, he grimaced widely.
She pretended to peer. "I think you got it," she said doubtfully. "And I'm not interested in your proposition."
