Slightly harsh I think. You may not wish to help, but others may do.
Personally had I been travelling today, I'd have guested her in, and would hope that if I were in the same situation (perhaps travelling with two guests) someone might be kind enough to help me out.
If someone stopped you at the entrance to the lounge and asked to be your guest, would you be equally "kind" and "helpful" ?
Has anyone tried this? If I hang around the entrance to the CCR, asking every F passenger if they can get me in, how long will it be before someone says yes? Please note I am "hot".
