Well if you can be playful when it comes to the teasing I don't see why she should be offended? Unless it comes out completely cruel! Sense of humor or not, every one likes a good laugh even if its about themselves as long as it isn't too harsh.
You can also do it that way just stop yourself from placing her on a pedestal!!! Go with complimenting her on the personality, avoid the looks compliments unless you can deliver them in a very Alpha manner. And finally go ahead and ask her for a drink, just don't forget to build to asking her!
