How can I buy beer when I'm only 20 years old?
<|assistant|>
In most countries, you are allowed to legally purchase beer when you are 18 years old. However, many places will still require you to show proof of age, such as with a driver's license or other identification. Check the regulations in your area to determine the age you need to be in order to legally purchase beer.
