One of us threw his tooth maintainer to the rubbish bin during breakfast. We desperately realised it during the journey to Jungfraujoch, so we chose to call the hostel and asked to hold the rubbish bag for us. Unfortunately, when we were back to the hostel, the bag of rubbish was not being held anymore because they thought we were not going back. What's reli nice is that the staff here went to the rubbish station with us and searched every single disgusting rubbish bag with us! We found it finally, thanks to the help of the staff.
