Welcome to Fluther!
Depends. We were invited to a dinner hosted by my husband’s boss, I nibbled at the food and yes, I tried everything. I didn’t get huge portions of anything, so I wouldn’t waste food. Nothing very appealing to me, I’m not a veal eater.
For “normal” places, my mom’s house, best friend’s house…no. We’re pretty honest with each other and I am not offended if they don’t want or like what I prepared. my best friend hates cheese (how can anyone just hate cheese?), I did an oops and make a dinner that cheese was a big factor, she had a sandwich and salad for dinner. She was ok with it, so was I.
