Well, it's not really a public bathroom but in a school bathroom.
1. Basically, I saw a bunch of kids throwing wet tissues at a student pooping inside the stalls. The student was like "Hey stop!" and it sounded so cringy that me and those kids throwing the tissues were hysterically laughing.
2. Somebody stuffed a bunch of tissues in the school bathroom's urinal and peed on the tissues.
3. Me and my friends found a little unlocked door in the school's bathroom for the 5th floor. When we opened it, we saw a small but tall hole behind that door. The hole descended from the 5th floor to the cafeteria and there was a f**king bunch of machinery and wires, was probably the place the lift went up & down.
