Before being able to open certain businesses, your character has to attend classes to be able to open them businesses.
Examples:
If your business sells alcohol, then you would need to attend a class to be able to sell alcohol just like the UK. This could be split into two categories, licence to sell alcohol in a pub or club, and the other would be like a shop where they sell alcohol to be consumed off the premises.
If your business involves food, then you would have to attend classes to gain a food hygiene certificate.
