Enjoy a burger how you want, or not, I could hardly care any less as long as you're not hurting anybody with your lifestyle choice.
Personally, I just don't like cooked pineapple very much. It's a pale imitation of fresh in both taste and texture. Pure disappointment, and I've got enough disappointment in my life already, don't need anymore on my pizza or burger or tacos or spaghetti or upside down cake or colada.
