This is why the offshore business is dying. A Vegas book will hand you the cash of your winning bet within minutes the game is over whether it's a $5 win or a $50,000 win. They offered you a line , you placed your bet on that line, it doesn't matter if the line moved before, during the bet or after the bet. When you handed them cash they accepted full responsibility of the placed bet.
