¯_(ツ)_/¯ My roommate and I order from a new-to-us pizza joint every other month or so and he frequently orders a pie with pineapple. I can count on one hand the number of places that actually had a delicious pie with pineapple.
Maybe my standards are too high, but you knights of pineapple can enjoy whatever you want.
I dislike pineapple on pizza because most places always do such an awful job. You either get pineapple chunks that are still partially frozen and waterlogs the pie, or you get desiccated husks of fiber. Any salty/sweet combo advantage is totally lost.
