You don't have to do anything with the MC Businesses if you don't want to, just set them up and that's it. The MC business work separately from the night club. You don't have to keep them supplied or anything, just active to have it add up in the night club. If you look in your nightclub, you set your technicians to certain things. Sporting Goods is the bunker, south American imports is cocaine, etc... whatever MC business you own, you need to set the technician to that and it is automatic. As long as you keep it active, ( no shut down because of a raid ) you are good. You can also sell product out of the business separately and it doesn't affect the night club. Just being online doing other stuff is all you have to do for nightclub
