Supplying alcohol to a minor without actually supplying?

What is the name of your state? Pennsylvania

While out with some friends last week, as we walked past a beer distributor, a young guy (probably around 19-20) stopped us and asked if anyone over 21 would buy him beer.

So, one of the people with us says sure, goes in and buys a 40 oz. with the money the young guy gave him, and comes out, but when he's in there, the young guy wanders off. The person who bought the beer ends up keeping it, and as we're walking home, a debate starts.

One side contends that the person who bought the beer could still get in trouble legally for purchasing the alcohol for the minor, while he contends that since he never actually gave it to the minor, he could not.

Just curious.. who's right?

We don't do homework.

He could still be charged.
