Nightclubs in GTA Online are businesses included in the game as a part of the After Hours update. Any of the ten clubs can be purchased at the Maze Bank Foreclosures website.
Franklin is able to walk with Chop after the story mission Chop. To walk and play with him, look for a bone icon on the map — it shows his location. Chop always waits near Franklin’s house.
Go to Chop, disarm and, while holding LT on Xbox, L2 on PlayStation or RMB on PC, press RB on Xbox, R1 on PlayStation or LMB on PC. Now you’re walking with Chop.
Now choose the ball as a weapon (it’s in the same slot as the grenades), and throw it anywhere. The requirement for 100% completion fulfills at the time the throw. It doesn’t matter if Chop will bring the ball back or not.
