Seriously people, use the fucking fan. It clears away odors and covers up the sounds of your dropping a deuce. If you want to stew in your shit smell and revel in the music of your magical poop plops, do so in the comfort of your own home. If you’re a guest and the bathroom has a fan, turn it on. We don’t want to share.
Do you ask your guests to turn the fan on, or just passive aggressively whine about it when they leave?
The irony of you actually being a passive aggressive douchebag by pretending the op might be passive aggressive is off the charts.
