We can delete a franchise in a way... Because of the Reservation that will be tied to a Customer we cannot delete a Franchise from the table. I have created a field that will makes a Franchise active or inactive. Vehicles will need to be deleted as well but I am sure that in real life as well but that will throw more error for the reservation. I will talk more about it at the next hack, since this would deepen the scope of the project for everyone and I am not sure if this is what we want.
