i agree with profesh about personalising, but lay off the cheese.
giving first is a good idea too! especially if you're good, then she'd probably be more than happy to return the favour.
or, when you're together, and starting off, just kinda lead her towards that direction, she'll get the hint, and if she doesn't want to she'll make it clear, and as long as she knows you're not expecting it and gunna go in a huff otherwise, she should be fine!
