If non-Mevushal wine was poured by someone who should not have poured it, what should one do? Does it make a difference if:
- the wine was poured, but not for you (ie., you just have to contend with the remaining wine in the bottle)?
- there is no other wine available (or no other non-Mevushal, un-poured wine) and it is needed for a mitzvah (קידוש, ד' כוסות, ברית מילה, ז' ברכות)?
- the pourer will almost certainly be offended if you don't partake? (Setting aside social reasons not to pressure someone to drink; let's suppose there had been a conversation moments prior about how excited one is to try the wine because of its uniqueness, or something like that.)
