I think I would. If I gave the person the money to go get it for me, then yes, I think I would. After all, I only spent a dollar, which I would have lost if I hadn’t won, so I’m still coming out with more money than I had to begin with. It wasn’t earned money and you aren’t losing any money by sharing it with the buyer of the ticket. Although, I would never expect that if the shoe was on the other foot that I should expect the same treatment, and I would never ask for some of the winnings, but I’d happily accept some if it was offered.
