To want ILs to have some table manners

[NigellasLoveBuns]

As I didn't want to hijack a previous thread I felt I had to start one.
ILs are really irritating when eating. They all eat with open mouths and make horrible chomping noises. They also talk with a full mouth and spit food all over the place.
As if that wasn't enough, on a recent visit to KFC we all "shared" a bucket of chicken. Won't be doing that again in a hurry. DH was partly to blame as I told him I didn't really like some of the things in the bucket. Still you would have thought that it was polite to ask what people want before just grabbing your own.
No that was really too much to ask, ILs grabbed what they wanted (with the usual "we don't eat much" comment. They grabbed it all and started eating while we were still getting the rest of the food.
After putting a tonne of salt all over the chips (they know I never eat salt with anything) I ended up with a few chips that we had rescued from the salt mountain and one piece of chicken
MIL also dips her chewed bread into my food. Lovely.
DH has had a word but did no good.
They are coming here after Christmas. Can't wait!

Poor you! Nothing like biting your tongue to keep the peace to give you indigestion!

Focus really hard on enjoying what you are eating, and keep your eyes away from them and their trough food. It's the only strategy that got me through family meals when I was a teenager.

If you ever end up in KFC again with them I'd definitely order yourself a separate meal rather than share anything with them! Even if it means they effectively get your share of the bucket and you have to pay more to get your separate nice meal, If they query it, you can just say that after last time you couldn't face more salt on your food and you wanted xxx not yyy from the bucket...

Or point out that they demolished pretty much the whole thing last time and you thought they would have wanted more so this is a treat for them...

How old are your dc? Are they old enough to do a bit of role play and for them to copy your pil and for you to tell them off about how rude they are being (having arranged it all in advance obviously so they know they are not really being told off and are getting an extra treat when pil have gone!) so you get to state stuff like eat with your mouth closed and hope they take the message?
