That is when we found out about the other guy had taken his money and disappeared. It took him about 1/2 hour(!) to finally find someone to check on the machines.
When we realized that the ticket was gone (my husband at first thought a different machine had 'eaten' it), he went to search for ANY security person.
We saw the person, but did not realize he was taking my husband's money. He got distracted for less than 30 seconds (established by their slot records), and someone put in a different ticket for $190, did not even play, but immediately pulled out $325.75. Around 10pm, my husband took $134.75 out of one slot machine and put it into a different one.
