Depends on how much I won and how I feel about the giver.

In general I see no obligation to, but if I had a huge windfall, I’d tend to spread it at least somewhat.

It has never happened to me, so I can’t be 100% sure what I would do.

Somewhat depends on the dollar amount. If I won $50, I keep it all.

If I were to win $1000, maybe give him/her $200.

If I were to win $1,000,000 I would give a couple of percentage points – maybe $10–20000

Bugger that into a rusty tin hat, the purchase was theirs the good fortune all mine.

I would give them back their dollar, or whatever they spent on the winning ticket they gave me.

Similar to @elbanditoroso , it really depends on how much I won. If I won @20 or less, nothing. $21 to $100, a latte or maybe breakfast. And larger for a larger jackpot, but not ten percent, and it would be a percentage after taxes.

Yeah, I would share.

@ucme, lol!

I too would consider according to amount.
If a large enough amount, I would probably give them option of cash, or come with me on world tour. That would depend on whether they could push around my chair.

I think I would. It’s partly gratitude and partly golden rule. It just seems right to share it.

I don’t think that anyone is obligated to share, but I probably would if it was more than a few dollars. If it was a large amount, I’d just split the money with them. Otherwise, I’d spend it on something for the both of us (like @zenvelo‘s breakfast idea).

Its rude not to take them to dinner or something.

When I buy a lottery ticket that wins, IF it’s below $100 I keep it all. IF it’s over $100, I tip the sales clerk 10%. Over the last 20 years, I’ve hit on the scratch offs for $500 twice. Each time I tipped the clerk $50.00. Anything under $600 is tax free; so, I give less to the sales clerk than I would to the government. Now, IF someone gave me a huge windfall, YES, I’d share. I’d hire a financial planner or lawyer to tell me the best way to share it!!! I think that they start out at $40 million; so even IF I share after taxes, I’ll still have enough to sustain me for most of the rest of my life!!!

I believe in karma & IF I’m greedy, I’d be bringing bad karma down on my shoulders. So, I have absolutely NO problem sharing my windfall!!!
