Before the days of bill feeders, I was hand paid for a jackpot that hit with the last of my credits. When it came time to "play it off", I told the attendant I didn't have any more tokens. Nevada Nickels. So the manager told the attendant to open the machine which he did and gave me tokens to "play it off". In your case, they usually do want the machine cleared before they leave so if you tell them you don't want to make another wager they should take care of it. IMHO.
