The quick turnarounds with shoddy grooming happen all the time. No surprise to anyone here, right? When I arrive to a filthy seat, I try my best to clean it myself and will enlist the assistance of an FA (usually a SD because they seem to give a damn much more than a regular FA) if I actually need it... Typically asking them for some wetnaps or a plastic bag or something.
But yeah, sometimes the filth piles up it becomes visually nasty. Those who I communicate with outside of FT have seen my pictures and heard my stories. I don't bother posting every single occurrence of my flying life here like others do.
