That’s One Way to Solve that Problem
Back in high school, my school did a week-long musical exchange program to Cuba. It was absolutely stunning and I enjoyed every bit of it. However, the place we stayed at was a resort, and each room was a tiny cabana that held 3-6 people.
Everything was going great the first few days, until one day we heard this strange gurgling while sleeping. The toilet water was overflowing EVERYWHERE. Not just for one night. The toilet just kept overflowing at the same time, in our cabana every single night until we left. We had no idea why.
It got to the point where we just started closing the bathroom door and clogging the bottom of the door with towels. We took shifts with replacing the towels.
