As with the other's you need to call your guests and get a firm head count. I see this all of the time, unfortunately, and honestly I think it's a cultural thing (that's just how some of us do sometimes).
Get on the phone with everyone who was officially invited and then as the negatives come in, ask those not previously invited that your fiancee's Mom has. And let those know who are adding guests, that you cannot accommodate them.
Despite what Trueeee has said, the caterer will not do a head count during the reception and give you a refund on food not served. The food was still purchased by the caterer and they need to cover their costs. |
