You've sensibly dispatched her to the kitchen?
The answer is "it depends on the situation".
In most cases the law requires you to be able to make the choice yourself, and endeavours to protect you in the event your consent was not gained fairly, however there are circumstances where the law permits others to make the choice because you cant.
2 that come to mind are when someone else has power of attorney over you and when you are in need of medical help and a suitably competent and/or empowered person has to make a choice on your behalf.
If the term "safely" implies they are under duress, then indeed, "yes" is not consent.
