Or...just rules of etiquette period!! When I sent out the invites I had to follow-up with phone calls to get a head count for the caterer. I think most people feel that you should have plenty of food and do not realize depending on
whether it's per plate or buffet style it still cost $$$$. Hmph!!!...I bet if we said there would be a cover charge; they would respond.
Oh...and what about the married vs. single guest. It is not proper to invite someone along as a date if you are not part of a couple or if the invitation has the invitee's name only. I had a few of my single male friends and ladies
who had the nerve to show up with the flavors of the minute. Help us Lawd!
