An ATM sign featuring the Master B8r logo.

Master B8r is a credit card company in Grand Theft Auto: San Andreas. It rivals Rockstar Cards, PISH and Pla$tic. Its name and logo are based on MasterCard and subsidiaries Maestro, and Cirrus. The logo can also be seen on page 13 of the San Andreas manual and on the ATMs in the mission "Small Town Bank". The name is a pun of the word "masturbator" and the real MasterCard brand.
