2~3 years ago, I had a balance of $400 in a sportsbook. I was scanning various lines, and suddenly my balance jumped up to approx. $8000!
Anyhow, I knew this was apparently a software glitch, and it would soon be corrected. I decided to have some fun with it, by playing blackjack in the casino. After about an hour, and still no corrections to my balance, I won around $2,000. I left for a few hours, came back that night, and instead of the $10,000+ balance that was in there earlier, it was now approx. $1400. I finally called, to find out exactly where my balance stood. After speaking with a couple of supervisors from book and casino, they told me my balance was exactly what it showed, $1400. They explained, and voluntarily awarded me half of the winnings I had in the casino earlier! How did they come to this decision? Well, they used the assumption that, I had $400 in my account at the time, and I could of very well won those profits off of my own money! Now that's how things should be done!
