Ah yeah, olives are another thing I'm not crazy about. I gave them another shot a short while ago and their taste is just... off and kind of distracting from everything else in the salad (usually what I find them in). My dad doesn't like olives either, and he doesn't like mushrooms on top of that (I'm okay with them, though I won't go out of my way to add them in myself).

I also don't care for mustard or American cheese (not fond of blue cheese crumbles either). With cheese, I'd WAY rather have Swiss, cheddar, or provolone. But yeah, quickest way to kill a burger for me would be to put American cheese, mustard, and mayo on that. You might as well dump gravy, peas, and orange slices on my ice cream.

And yeah, I get the thing about textures. That's what really got me as a kid. If something looked messy or slimy, I assumed it would taste terrible and wanted nothing to do with it. So something like a burrito or a pot pie would terrify me as a kid, but now, hey, those are pretty good.
