The Joybooth makes an appearance in 2041 and 2071. In 2041 you activate it by wearing the headset and putting your credit card in the slot. In 2071, you activate it by wearing the headset and pushing the button.
JOYBOOTH-BUTTON is moved to JOYBOOTH by SIMULATION-ACTION when you enter the 2071 simulation. But it is never removed, so if you enter the 2071 simulation, exit it and then enter the 2041 simulation the button is still there. So you can get the 2071 experience in the wrong year:
>LOOK
Joybooth
You are in a Dizzard-brand joybooth, the most expensive but generally considered
the most well-programmed line of booths. The room is small, barely a meter
across, with gray carpeted walls, a slot for credit cards, a headset, and a
plain, built-in seat.
>DATE
Today is 6/3/2041.
>WEAR HEADSET
You are now wearing the headset.
>PUSH BUTTON
The walls of the joybooth recede, and you find yourself in an arena, garbed in
magnificent gladiator's armor. In one hand you hold a long whip, in the other a
mace. The ground around you is literally soggy with blood.
You barely notice as the headset probes into the recesses of your mind,
uncovering hidden thoughts, nurturing certain emotions. An unclad, unwashed
barbarian suddenly stumbles into the arena before you, and at once your mind is
filled with unthinking hatred toward this...this thing, this animal.

I think the appropriate fix would be to add <MOVE ,JOYBOOTH-BUTTON ,LOCAL-GLOBALS> to JIGS-UP, similar to how the game removes ROY from any other simulation than the 2071 one.
