Out of all stores, only one has a mission appearance. One of the stores appears during the mission Shima for Kenji Kasen in Grand Theft Auto III, when Claude goes to one of the stores to collect the protection money for the Yakuza, only to find it wrecked and robbed by some Diablos. After getting yelled at by the supermarket's clerk, he drives to Hepburn Heights, kills several Diablo gangsters and gets back the protection money they stole.
- A hidden package on the roof of the store seen during Shima.
- "Uncle BJ's" is another instance of Rockstar's adult humor. "BJ" is short for 'blowjob', a slang for oral sex.
