It winds me up more and more these days that having friends over for dinner involves getting the list of the things they can't or won't eat and then working out how to cater for them. Particularly, this is a problem with my DH's friends' WAGs who all have either a wheat, dairy or red meat "intolerance".
So I enjoyed India Knight's column today That?s no food allergy, just bad manners
On the other hand I don't mind at all catering for friends who seem to have a genuine problem or religious/moral stance - one of my best friends is a coeliac, one halal, another is a vegetarian for moral reasons.
