David,
I know from what you have said elsewhere on the forum that you are planning to open up your own pizza place. Most pizza places use the standard California or similar black olives that you do not appear to like. On occasion, a pizza operator will use something like a Kalamata olive, but most often that olive is reserved for specialty "Greek" style pizzas, with feta cheese, onions, artichokes and the like. I know that you registered recently at the PMQ Think Tank, so you might want to post your questions on olives there to get reactions from commercial pizza operators, just about all of whom offer olives as one of the available toppings.
