Final answer:
No, you cannot display either a Sandy's Law sign or a Liquor Sales license in a licensed establishment.
Step-by-step explanation:
No, you cannot display either a Sandy's Law sign or a Liquor Sales license in a licensed establishment. Sandy's Law does not pertain to the display of signs, but rather refers to laws that forbid or compel certain forms of expression by businesses. Liquor Sales licenses, on the other hand, are usually displayed in establishments that are legally permitted to sell alcohol. These licences serve as a legal authorization to sell and distribute alcoholic beverages. Therefore, displaying a Sandy's Law sign or a Liquor Sales license would not be appropriate in a licensed establishment.
