The legal age requirement for working behind a bar or handling alcoholic beverages varies depending on the country and local regulations. In many places, the legal drinking age is higher than the legal working age, which means that even if you are not of legal drinking age, you may still be able to work in establishments that serve alcohol.
However, it's essential to comply with the laws and regulations of your specific jurisdiction. In some places, there may be restrictions on certain tasks or areas within a bar for individuals under a certain age. It's crucial to check with the local authorities or your employer to understand the specific rules and requirements in your area.
If you are underage and interested in working in a bar or handling glasses, it's best to inquire with your employer or seek guidance from the appropriate authorities to ensure that you are in compliance with the applicable laws and regulations.
