so, I've noticed that I'm unable to get the last union card that I need to finish the game properly, due to handing the car person the wrong tape, is there anyway to fix that?
there’s no wrong tape to give them, either tape proceeds the quest and they will always give you an item after.
With that item, you can actually now go to the computer in the department store manager’s office and go to the last tab in the Self-Help Program.
After that, go back to the npc in the car to get the Union Card
