He's super vain. If you aren't up to his standards in terms of looks, he won't care who you are. This doesn't mean just your appearance, but also your clothes, your perfume, the way you speak, etc.
He runs a club so he will pretend to know you even if he doesn't care. Expect a lot of 'dear', 'darling', 'gorgeous', mostly because he doesn't remember people's names. You can find a description of Wonderland here
