From The Grey House:
Anthony arrived before the waiter returned, so Vincent made light talk. When two goblets were presented to him, Vincent smiled, thanked the man, and slipped him three twenties. Vincent believed strongly in rewarding loyalty.
Anthony smirked at the gesture, clinking goblets with his leader. “You pay them more than anyone else. Why tip them for wine?”
“It’s not wine.” Vincent stated between sips. The liquid held no sustenance; the taste was all he wanted.
Anthony took a small sip. A look of real surprise crossed his face. “How?”
“I get what I pay for.” A mischievous smile floated across his face, then faded. “What have you learned?”
