If you enjoy a flutter at the casino this is probably your worst nightmare.
Katrina Bookman, a single mother of four, was playing the slots at Resorts World Casino in New York when all of a sudden the machine she was playing hit the jackpot.
When she looked at the screen she was informed that she had won an astonishing $42.9 million (£34 million).
Well, you can imagine just how delighted Katrina was. She even took a selfie with the machine.
Woman sues casino that offered her steak dinner instead of a $43 million jackpot https://t.co/bDH4MX9RdE https://t.co/ABQWWLNlf6 — CNN (@CNN)
That's when things began to get a little suspicious.
The casino security asked her to come back the next day and collect her sizable winnings.
Except that didn't happen at all.
When she returned Katrina was informed that she hadn't won millions of dollars but that the machine had malfunctioned and displayed the incorrect message.
Unfortunately she had only won a measly $2.25 (£1.70) but the casino were feeling generous and offered her a complimentary steak dinner in compensation.
Dan Bank of Resorts World told CNN:
Casino personnel were able to determine that the figure displayed on the penny slot was the result of an obvious malfunction - a fact later confirmed by the New York State Gaming Commission.
Katrina doesn't accept that though, and she has hired lawyer Alan Ripka to see whether a casino can refuse a prize based on a malfunction.
They win and the house doesn't want to pay out. To me that's unfair. The machine takes your money when you lose. It ought to pay it when you win.
Katrina is now trying to sue the casino for the full amount she supposedly won, or at least the maximum which is allowed on the machine $6,500 (£5,086).
People on Twitter have definitely got her back.
