One of my roommates was recently invited to a wedding of a friend from high school. She is single and didn't receive a plus one. She wasn't upset at all and figured she'd find people she knew to sit with or be seated with. The wedding is in two weeks, and she long sent in her RSVP. Last night the bride texted her to let her know that if she wanted to bring a date or guest, she was more than welcome. Obviously they had enough declines where they now have room for single guests to have plus-ones. My roommate was excited and asked a guy friend to go with her, but in my head I questioned it - her friend essentially B-listed the plus ones for the single guests.
I know single guests don't have to have a plus one, so it was fine for them to invite my roommate alone. But is it ok for them to give her one since they had space?
