If Andy orders a Jack Daniels shot, what are you allowed to serve him?

When a customer orders a Jack Daniels shot, the appropriate response is to serve them Jack Daniels specifically. This is based on the principle of honoring a customer's request for a particular brand or type of spirit. Jack Daniels is a well-known Tennessee whiskey, and when someone specifies it, they expect that exact product due to its distinct flavor profile and reputation.

Serving any whiskey would not meet the customer's request or expectation, as there are many varieties of whiskey that differ significantly from Jack Daniels. Offering non-alcoholic drinks would not satisfy an order for an alcoholic shot, and mixed drinks only would also not align with the direct request for a specific shot. Therefore, the correct response to Andy's order is to serve Jack Daniels.
