I think my taste for black olives was ruined by crappy pizza.
Have you noticed that when a bulk pizza order is provided by a company or a school or a club as a fun treat, black olives are over-represented as a topping?
My conspiracy theory is that giant cans of pizza-grade black olives are cheap, but they count as "a topping" so the restaurant can ship a pepperoni-and-olive pizza and count it as a two-topping pizza with the most profit. When Mgmt is ordering morale pizzas, they usually just tell the pizza restaurant "get us X pizzas in your recommended topping assortment," so it's olive time.
I just plain don't care for olives, though. I'm fine with cheap olive oil as an ingredient, but EVOO has an aftertaste. I will not be taking questions on this as it is a matter of individual taste, but EVOO is like chewing on the sprues from a model car kit.
