Isn't a safe where his money was stolen from? I haven't watched that movie in a while. Potter fleeced George as I recall, but maybe I'm wrong.

No, his money wasn't stolen from the safe. Billy (George's uncle working for/with him) accidentally left it with Potter at the bank. Potter unsurprisingly kept the money and pretended he didn't know anything about it when Billy came back to ask where it went.
