Dude. Your problem is not the pineapple, but that you are apparently surrounded by inconsiderate people.
If you get pizza or any food to share, you should make sure you choose a topping everyone is okay with. If necessary make it half pineapple half pepperoni or whatever.
If you order for a group of people and choose something that is controversial without checking back, you’re an asshole.
Is this the proper English word? Cockeyed? COCKeyed?
