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.
I went into a public restroom in a gas station once that was set up with a motion sensor. But I didn’t immediately know that. It kinda freaked me out for a bit when after like 3 minutes the entire room went pitch black dark. I thought their breaker kicked off or something, while sitting on the toilet.
If it’s gonna be on a timer, it ought to be set for more like 10 minutes or something. I dunno about everyone else, but I don’t tend to do much of any significant movement when sitting on the toilet to keep the lights and fan on.
