To be irritated by false praise?

[Thistledew]

It's only a minor irritation in the scheme of things and most of the time I just let it wash over me, but I do wonder if IABU to be bothered at all.

I regularly cook for someone who is a fussy eater. She is unfailing complementary about my cooking and therein lies the rub: she will be just as thankful when I serve her a complex and carefully prepared dish of things I know she likes to eat as when she is eating nothing but half a buttered baked potato (because she has suddenly decided that she doesn't like the topping, despite it being something she has eaten with apparent enjoyment several times before).

I don't think she sees that it renders the praise of the fancy dish meaningless if she effusively praises the baked spud as being "fantastic and delicious".

AIBU?

My Mil does the really over exaggerated praise thing in a really patronising way 'OH WOW this is just so delicious, god you're such an amazing cook'. OK thanks but I just heard you announce to everyone in a ridiculously loud whisper that it was overcooked. Once she was visiting us and I'd spent hours cooking a meal for her first night. She decided she really fancied cheese and crackers instead but ate a tiny morsel of the meal and wouldn't stop talking about how great a cook I was. (She's actually a nice person just very very territorial about cooking).
