Complimentary Voucher

The complimentary voucher is a miscellaneous item

Obtainment and usage
Winning 7,500 chips at the Sierra Madre casino will award the complimentary voucher, and is the final reward tier before the player character is banned from gambling there. This will allow the redemption of vouchers for 1,000 Sierra Madre chips (listed as "Free Chips") at the vending machines. If one did not redeem their first voucher before leaving the Sierra Madre, then they will not be able to redeem any vouchers in the future. As a result, the complimentary vouchers that are received every 3 days at the Abandoned Brotherhood of Steel bunker will be useless, as the vending machine will not accept them.

Bugs
They may float in the air where dropped. The player character is unable to walk under it, but they can jump on it. This can be exploited to make shelves and bridges wherever the player character may need them. This can also be exploited to reach the Legate's camp earlier in the game.
