You Offered Me What?

There's this little story in the news from a while back that you might find interesting. Bob Kitts, an Ohio contractor, was working on renovating a Depression-era home and he found a little something in the walls - that little something was $182,000 in cash! 

Well, the homeowner was kind and grateful and offered him about 10%.

I guess he's now suing for all of it. What do you think? Would you accept 10% because at least it's something, or would you think that they never would have found anything so you should get it all, or at least more? Would you have told the owner in the first place?
