Table 20
I love the sense of humor of this bride and groom. The concept of RSVP-ing does seem to be lost on some people, and I spent my fair share of time before my wedding chasing up whether guests were actually going to attend before I made the final call to the caterers.
An alternative solution is to put all the inconsiderate attendees who didn’t bother to RSVP on one table, all the way at the back, with labels that make sure everyone knows how they acted. That way they still get to attend, and you still get to make your point.
