I have bad social anxiety and pick my social situations carefully
It fucks me off so much when this happens (and then it seems like I have a problem with the plus one which I almost never do they're usually great I just don't want my comfort zone changed without my participation in the decision).
My mother in law does it a lot which as you can imagine is a whole extra layer as my husband can't cope with her being upset (he does side with me he's still just very upset about it).
