Nah man. He's in the pineapple capital of Australia. If I go to Italy and order pineapple and ham on pizza, sure, I'm in the wrong. That's not a cultural thing they do there.
But this dude wasn't in Italy. He was in a place where pineapple is insanely popular. The culture there is to put pineapple on things. They put pineapple in places you'd never expect pineapple to be because that's what you do when you have a lot of fresh pineapple. He lives there. He knows that. He's a chef, he should know better.
Now excuse me, I'm going to make a pineapple canoli because that sounds dope.
