A customer tipped his waitress at the Sup Dogs Restaurant in Greenville, NC after paying for the bottled water he’d ordered. It was a big tip. It was a very large gratuity. It was enormous, says the Association of Mature American Citizens [AMAC]. To be exact, it was $10,000 worth of thank you’s. The waitress was taken aback but didn’t forget her coworkers with whom she shared her good fortune.
