OK. For starters, it's a 4P, not a StR. Looking at your photo, I see no dirt or mold. It's the natural little bit of extra soap, that last drop which is sometimes smeared as someone pulls their hand away. Is it perfectly clean? Nah. Is it up to standards? Undoubtedly not. But you had to bend down to look up at the dispenser to see it, didn't you. I can't view this as a war crime. I agree, it shouldn't be that way. But in the comprehensive catalogue of theoretically possible housekeeping failures, this particular one really isn't terribly high on the list, given that there is no mold, no dirt. At least not on my list.
