I know this sounds like a silly question, but has anyone ever seen a FA clean the washroom during a flight? I see them going in and out of there, briefly, and I assume they are checking on supplies, etc.

There have been a few times I wanted to use the restroom, but someone had literally soiled it.

Maybe this isn't the job responsibility of the FA's? I have no idea. I just wish I could use a clean bathroom when I'm 5 hours into my flight to London, etc.
