If you make a list of every letter that's capitalized that shouldn't be, you get: LFTWTMPI. Then, if you add the letters that aren't capitalized but should be, you get: mcLFTaWMPI.

My best guess is that it's a coded anagram message, which reads:
LIFT MaP TIm Wc. 

Is there anyone out there named Tim who's using the toilet and looking for a map? I believe this message is for you.
