Suddenly a loud buzzer sounds, the lights come on, and your gun switches off with a click and a hum. "All right, people," the operator says over the P.A., "we're closing up here. Please exit the arena, and enjoy your new lives!"
New lives!? This can't be right! Frantically, you try shooting yourself, but the gun's not responding. You make a mad dash to the operator's booth and beg him to change you back.
"I'm sorry, Miss," he says, "but that was a permanent-change game you walked in on, as was clearly indicated on today's schedule. Your legal identity has already been changed to reflect your new form."
"B-but can't you ch-change me b-back j-just this once?" you stammer. He shakes his head. "Sorry, Miss, company policy. These events are expensive to put on, what with all the paperwork that needs to be filed, so we're not allowed to make exceptions, ever. If I were you I'd just go home and get on with your life."
He takes your equipment back and locks up the booth, leaving you standing there, a confused and frightened vixen facing an unexpected lifetime of womanhood.
