This is kind of funny and kind of obnoxious on my part, I ordered some wine on a recent flight sitting in economy, the FA had that device in her hand and then asked me for payment. I told her as a concierge key I do not have to pay. And she said only executive platinum’s do not have to pay everybody else has to pay. I repeated I’m CK. She repeated only EPs do not have to pay. I said, “look up CK on your device.” She came back minutes later apologizing.
