We got our first RSVP from a guy telling us he was bringing a "guest." Not only does this guy NOT have a steady girlfriend, but we didn't want to invite him in the first place (long story...). So for him to ask to bring a guest? uhuh.
Here was my response to him via a FB message:
We got your invitation today! But unfortunately, our budget and space at the venue is extremely tight, so because of that, we can't accommodate additional guests—I had to even make some guest list cuts to family friends.
I'm so sorry and hope you can still make it!
Ugh. I hate awkwardness, but seriously?! We had to cut some of my favorite family friends just to make sure we have enough room, so I definitely don't want some guest I don't even know. I hope that was polite enough.
