Scenario: You work in a small, rural town where you visit the same convenience store everyday. You see the same cashiers all the time. Imagine one of them sells you a Powerball ticket. Said cashier is a friendly college girl who has worked at the same store for 3 years. You go to have her check it for you the next day, and find that you hit 4 + 1 (the level just below the jackpot) and win $40,000. She's genuinely happy for you, and congratulates you repeatedly.
After you collect the winnings, do you tip her? And if so, how much?
