We had a winner of a $220M powerball jackpot at the store where I buy my tickets. The owner of the store, the Cumberland Farms Co, received a bonus of close to $440,000 for the ticket and they did share it with the employees of the store, giving generous shares of the bonus.
Many of the employees of that store still sent letters to the winner asking for more money, telling their sad stories. Further, having spoken with these people and having discussed the subject, I can tell you that any amount given would not, in their minds, be "enough." I have discussed it with the employees and they all express resentment that they were never contacted by the winner, who never set foot in the store again.
In fact, the $220 million figure is a fiction. The cash value is half of that, and then there's taxes, taxes which happen to be higher than the "withholding amount." If the winners realized 80 million - and maybe they didn't - I'm sure they know at least 80 people - including the 20 or so employees at that store - who feel entitled to "just a million."
Actually, if you win the lottery everybody and anybody wants your money. The store employees did nothing more than their jobs and they are not really any more entitled to any money than your long lost cousin who just happened to hear about your good fortune and wants you to contact him.
I actually think the winners - a married couple - in this case have an excellent chance of keeping their money. Winning the lottery doesn't mean that your a fountain of money for every person you have ever known formally or informally.
If one seeks to be generous with his or her good fortune there are plenty of legitimate organizations with serious needs to which one cannot donate.
If I win the lottery, giving tips to store employees would be the last thing on my mind. To be perfectly frank, over the years I've met lots of store clerks who openly express their annoyance at having to sell you a ticket.
