I have found money in casinos $5 bill on the floor in Harras, Sad to say I later donated much more than that. I should have stuck to my original plan with the money which was to put it in a machine hit the button and take that win or loss I would have walked out the casino with $11 to my benefit.
I have found chips on the floor usually $1 but they are free. Knowing how much I have donated to the casino's the best thing I can do with one is avoid it. Over a life time I might have lost about $1,500. To some that is nothing but it is something when you later need the money. Glad to say I have not needed the money as of yet but rather keep the odds on my side and avoid casinos' like they are poison.
When asked "Have you seen anyone come out on top by gaming in casinos?" Steve Winn said "no not one".
