The Great Incontinence Conspiracy

The goal of this conspiracy is simple, to prevent our protagonist from making it to the toilet in time. It doesn't matter where she ends up going, just so long as it's not in a toilet.

The methods of getting this to work may vary. For example, someone might try to sneak diuretics in her drink, they may try to hog the bathroom, or they may try to tell her it's out of order. Sometimes they will pretend not to know where it is so that she takes longer to find it.

So who is our unlucky lady?
