Creatine and milk

[JaimzTF]

I was talking to the owner of the local GNC and I was asking about my fav protein shake called anabolic activator witch is really hard to find. It contains creatine already in it. It says on the package you can even mix it with milk. I couldnt find any of the stuff i want at a decent price so i told him i just mix in creatine with my whey protein and milk. But to my surprise the owner said that milk destroys creatine therefore defeating the purpose of having it. Is that true?
