My friend is having a wedding in 2 weeks' time. My coupled up friends' partners have all been invited, but those of us who are single are not allowed to bring a plus one. The partners of my mates aren't even close with the bride or groom. I asked if I was allowed to bring my Mum as a plus one and my friend said she would let me know how many numbers there were for the evening reception.
Does this seem like a common practice at weddings ? Or unfair ?
