I can deal with black olives on pizza, but otherwise ick
I have a long list of condiment dislikes:
mayonnaise (cole slaw is okay if not too mayo-heavy)
vinegar
salad dressing*
mustard
horseradish
pickle/relish
wasabi
Also hate edamame and capers, and a million other foodstuffs I'm not thinking of at the moment. Not crazy about green peppers, but it depends on the use. I'm a picky eater.
* Especially ranch and other mayo-based dressings. I can tolerate an occasional vinegar-based salad dressing, if applied lightly. Usually I just get salad dry, or with a lemon wedge. You get a lot of funny looks ordering a salad with no dressing.
