A person who is a native BE speaker, did me a favor. I said thank you, and this person responded with "pleasure". I know about the response "My pleasure" or "You´re welcome". Is abbreviating it to just "pleasure" commonplace and considered a "normal" thing to say, and is it mostly a BE thing? Also, why would somebody choose the "pleasure" response" over "you´re welcome"? Is there a difference in meaning or emphasis or anything?
