It was the day of the swimming festival.
In the email, it was stated that we were supposed to enter via the back entrance of the public pool. Even though our school had its own pool, the diving boards and male change rooms were going through renovations, so they decided to host it at the local public pool instead. Obviously, they booked th entire pool, so there weren't going to be any members of the public in here. Still, we were forced to enter through the back 'entrance', which looked more like a run-down storage gate than an entrance.
