Pamela the waitress -speak when spoken to!

We were at spur in beacon bay retail park on the 06th Aug for dinner.When my sister went to pay,a lady called Pamela asked her\ u- on duty na?"in a very sarcastic way. Loosely translated as- are you still on duty.Simple because she was still wearing a work name badge! Who on earth and in her rightful mind will be on duty and still come to Spur???We might look stupid but at least we wouldnt come here when on duty.Generally this Pamela lacks professionalism and ettiquette.
