I just had my first potty-untrained grown up stay with us! We don't go into the bathroom our guests use until they leave or if they need something replenished. Needless to say, this guest only stayed two days but left a puddle of urine on the floor and all over the toilet. Not cool! He had left poop on someone else's toilet so I'm counting my blessings, I suppose. Cleaning fees are not sufficient for this kind of crap, no pun intended, IMO.
Adding this new point to my profile now and a note in the bathroom since, yet again, the obvious has to be pointed out.
