I am getting annoyed with some of our guests. The problem is, I don't know which guests to get annoyed at. We have received three response cards without all the needed information. Two of them said they were coming and didn't have names associated so I don't know who is coming and the third one didn't have ANY information on it whatsoever. No names, no markings as to whether they are attending or not and no number of people. It was completly blank. Is anyone else having this problem?
