I had the same experience and confusion when traveling to SYD over last Easter weekend - circled around a bit to make sure I wasn't missing something, and wondered how the heck they call that "valet"?!
At least she said "thank you" when I got my keys on the way back!
Incidentally, it was raining on our return and managed to get quite wet!
Thankfully, used the GE vouchers for that one.
