'Are you sitting down?' negotiations

Temat przeniesiony do archwium.
'Are you sitting down?' what exactly would it mean? e.g. do you agree on that? i'm not sure

I mean negotiations context
what exactly do you want us to tell you? It literally means "Siadasz?" - but what does it have to do with the negotiaions context??
przykladowo:
jezeli przez telefon ktos ma do przekazania jakas /wiadomosc/ ktora moze cie bardzo zaskoczyc moze najpierw spytac "Are you sitting down?"
/wciaz szerszy kontekst by sie przydal/

can anyone help?
Ten gosc na youtube nazywa ten i inne zwroty absurdem. Kto wie jakie ma to znaczenie w kontekscie.
Too genuflecting" or something between the lines of "acquiescence", implying something like " Ok, it's fine by me if you say so. Deal. Do you want me to polish your shoes now ?" :)
