Bring enough meat (pork was the meat of choice this week) to feed 5 adults and 4 kids?
Is this normal? 
I'm still in touch with ex MIL/SIL for DD's benefit, we are visiting them today as they called yesterday to invite us to Sunday lunch as they sometimes do. I got a call an hour saying "Oh btw, can you bring some pork with you?"...
It's happened a few times now, short notice, "Can you bring some chicken with you?" - cue me dashing about like a madwoman to get to Asda before it closes at 4pm to get meat and then get to them 20 miles away.
Part of me thinks IABU but most of me thinks that it's fecking rude to invite someone to lunch, and then basically tell them to bring enough meat for every one.
