They came from outer spice

I was quite perturbed by the idea of SF Chicken, though I suppose if you cross a chicken with something tentacled then everybody gets a drumstick. However it all made more sense when I remembered these adverts.

Three questions of etiquette

1. Is there any non-offensive way to say to people (who have misinterpreted our probably-confusing invitations-and-website nonsense and RSVPd to say they will be pleased to come to the wedding) "I'm sorry but the invite was only to the reception (because the actual wedding is v small)"? I just feel as though any way of saying it feels really horrible but we honestly can't fit everybody in. :-(

2. Is it even worse to ask this on my LJ where a) inevitably some people reading this will not have been invited to either (all other things being equal, this would still be a world-readable journal and the venue would still be finite) and b) everybody will think "oh noes are they talking about me?".

3. Might it be better to just shoot myself now?
