To despise picky eaters?

[Brownoliveskincurlyblackhair]

If you have an allergy or religious reasons not to eat something, fine obviously but grown adults who 'don't eat' something absolutely irk me beyond words. My MIL looked horrified earlier when I said I was making chicken as a part of a weekend spread because SIL 'doesn't eat it'. I have accommodated for SIL but honestly, I was bought up that you get what you're given and eat what's infront of you. It's terrible manners is it not?

Yabu - hosts should cater for preferences
Yanbu - it's rude

I wonder if it was the heatwave making her say strange things lol

I have no problem with fussy eaters. I do have a problem with capriciousness, and, to be fair to OP, it does seem that SIL falls down a bit on that front,
