My mum was raised without eating pork (they just didn't have it growing up), and my dad saw and heard the abattoir near daily and associates the smell of pork with screaming children.
On the odd weekend when they were both away, us kids would sprint to the store, grab reams of bacon and cook it fast on the sly for a real fry-up. We'd have to air out the house as well afterwards to get rid of the smell, but they'd always know and complain about it when they got back
