I have sold several of these. The biggest surprise was one client that went through and ordered only the tongue and other goofy shots.
Just as an aside, nose licking is most often a sign of stress in dogs no matter how cute we silly humans think it looks. When you get a dog that is more stressed, you'll see a lot more nose licking. Noticing this and other signs before the stress gets out of hand is great for managing the session and keeping fido happy.
