We decided not to include plus ones for our truly single guests, but are obviously including everyone's SO. Well I just asked one of the women at work for the name of her bf, as she had told me a couple weeks ago she was seeing someone. She gave it to me but then said, don't be surprised if I bring someone else. I'm thinking I should just let this slide and let her bring whoever she wants; we budgeted for her bf anyway, but I was wondering how the rest of you are planning on handling situations like this if they come up?
