Here in the Aveyron they are checking on all B&Bs to make sure they are registered with the maire and also have the correct paperwork.
You cannot sell beer and wine separatly but can offer it as part of your meal.
All B&B should also have a little sign up outside with the rates showing for rooms and meals. (Like a hotel)
As times are getting tough hotels and restraunts are not happy about B&B offering meals and rooms so that is why the new rules are beginning to be checked.
