Someone on Reddit posted a photo of their crazy office bathroom policy. If they take longer than 10 minutes, someone goes in after them to do a "SMELL CHECK"...to make sure they were really doing their business, not just playing on their phone.
The sign on the bathroom door says, "If in bathroom for more than 10 minutes, a smell check will be completed to ensure employee [was] not sitting on [their] phone. If it does not stink, employee's name will be reported to [the] office."
YIKES! Sorry to the person who has to perform the check.
