zahavasdad,
“Having a food at the table that literaly makes you nauseous does not make a good seudah.”
Agreed, though such a visceral reaction to multiple foods in an adult seems unusual to me.
“and the other item I will only eat begrudingly if someone serves it to me in a plate and I dont want to be a rude guest. I will eat it sort of the way a kid will eat Vegiitables that they hate.”
Well, you are an adult, not a kid, and I think you should conduct yourself as an adult at someone’s Shabbos table. That means having the ability to politely decline to eat foods that you do not want. Most hosts serve a plethora of foods to guests at their Shabbos seudos, and it’s impossible to eat everything on the table. I would much rather a guest politely decline a food on my table than to eat it begrudgingly, thinking they are pleasing me! And by politely decline, I mean, “no, thank you”, not “eww yuck, dats so gross!”
