How would you react to being offered $100,000 USD?

Here’s the scenario:

While traveling to a US state that is at least a 3 hour flight away from your home and is a state that you hardly ever go to, you purchase a Powerball lottery ticket. That ticket wins $4, but the drawing happens after you’ve returned home.

3 months later, your best friend who lives in that state comes to town (they recently moved there if they currently don’t live in a US state 3+hours away by plane). You give the ticket to that friend since you have no plans on returning to the state before it expires and there’s no remote redemption option. Your friend never plays the lottery, to the point you have to explain to them how to redeem the money for cash.

Two months after that, your friend calls you excitedly explaining that the night before they finally cashed in that ticket and played the Powerball with the winnings and hit the jackpot for just over $300 million USD (cash option, but before taxes)! They are over the moon and want to show their appreciation to you by giving you $100 thousand USD.

Here’s the question:

Do you simply accept the $100k? If so, are you solely grateful or is there any resentment that the offer wasn’t higher? What amount would be “fair” in your option?

Or, do you request a different amount? If so, how much? And if they refuse to offer anything more than the $100k, how does that change your relationship with them? How far do you push it (I don’t believe you have any legal claim to the money, but that doesn’t mean you can’t sue anyways)?
