What should you do after emptying a liquor bottle?

After emptying a liquor bottle, scratching off the tax stamp is the correct action because it is a requirement in many jurisdictions. The tax stamp serves as a marker indicating that taxes have been paid on that specific bottle of alcohol. By scratching it off, you are marking the bottle to signify that it is empty and that the contents have been removed. This process helps ensure compliance with local laws regarding the handling of alcoholic beverages.

Returning the bottle to the supplier is not a standard protocol unless there is a specific issue with the product that warrants a return. Recycling the bottle may seem environmentally friendly, but it does not address the legal obligations associated with the tax stamp. Disposing of it in the trash may also be viewed as improper handling from a regulatory standpoint. It's crucial for bartenders and establishments to follow the correct procedures to maintain compliance with alcohol regulations and avoid potential penalties.
