If you don't lose at the games, they'll find somehow to steal it from you.
I tried to cash out my ticket for $5.35 (I'm not much of a gambler, and the smoke was unbearable, so I decided to leave after a few minutes). The ticket redemption machine didn't work. I pushed all of the buttons, swatted it, and left, telling the security guard that the machine ate my ticket. he told me that if I waited 15 or 20 minutes, someone would come and see what they could do. I didn't want to wait 20 minutes for the possible (?) chance of getting $5 back, so I left.
