Basha, I have learned you never assume something. Just because Bob turned up with Carol does not mean his significant other isn't Alice!!
If the host does not name his/her partner during the booking process I will only mention the partner by name if I am invited too by both!
I don't want my listing to be the catalyst for a relationship break-up, and it's not for me to assume that Carol is in fact anything other than the bosses private secretary!
Unless you are invited to, only mention the guest who booked by name, don't even add, 'and partner'.....that could also lead to a difficult bit of explaining!
The only thing we need to know is what the guest was like, not who they might have had with them!
Cheers........Rob
