Looks like the letters C-A-S-H on this keypad would be 2-2-7-4. You type the code in. The action feels vaguely familiar somehow, like deja vu, but truth is you're not sure why.

It works! Thank you Nutregard, may he rest in peace. The screen starts flashing, and the ATM informs you that you somehow managed to figure out the security override code. You'd hoped that it might sound impressed, but it doesn't. Whatever, you don't care about its approval anyway. (That's a lie, you do.) You step back as instructed.
