There was me, getting all excited that I was going to have a free breakfast and the bastards quite unceremoniously uninvite me. I think I'll turn up anyway, stuff my face and say I didn't get the second email. Or shall I write something nasty back?
Please be aware that I had no intention of coming to your snobby EMEA christmas brunch anyway but thank you so much for uninviting me...
