When I registered for Lufthansa FF, the form was just numbers. My birthdate has two single-digit numbers in it, and I ended up with Month-Date backwards (US vs. rest of the world conventions - e.g., 4/8 is either April 8, or Aug 4).
It wasn't an issue, but a minor annoyance to fix it every time I traveled, so that it matched my travel documents.
Until a couple of years ago, when I was traveling back from Germany and the flight crew thought it would be nice to surprise me with a bottle of champagne at midnight on my "birthday".
They were so proud of doing this over the top "random kindness" (it was pretty thoughtful), and couldn't figure out why I was confused and annoyed. I still feel bad for not acting more excited or grateful...
