A similar thing happened to me years ago while working a graveyard shift at a gas station. Somebody came in late at night and projectile shit all over the top of the toilet and the wall behind it. Never seen anything like it in my life. Your description was perfect tbh haha… But anyways… Yeah I didn’t clean that shit. I left it for the next person coming in… Pretended like I never noticed it. I felt bad for whoever cleaned it but my minimum wage making ass wasn’t about to clean up liquid shit that was sprayed all over a wall
