Defecating my clean toilet!! (Light hearted)

[Square82]

So, I work in a large dining franchise as a cleaner. I love my job, where I work and the people I work with.
First job on my list is cleaning the male and female toilets at 6am. I love cleaning toilets (yes, I'm aware I'm weird and quite proud of it).
Management come in for their shift at 8am. All managers are fantastic....up for a chat, appreciative and let you get on with job.
There's one manager (male) who, once the caffeine and nicotine has kick started his bowels, will go in the disabled cubicle in ladies, drop the kids off at the pool and then casually walk out leaving the most horrendous smell and skid marks down my beautifully cleaned porcelain throne.
AIBU to expect him to clean his mess (there is a toilet brush) or should I, as cleaner, be in tune with his movements and clean up after him?
Just to add, he knows they're cleaned first thing in the morning.
This is meant light hearted and just me having a mini jokey rant.

Just say it to him.

Just mention it to him.

Remind him to use the loo brush.

My OH is well trained at taking toilet paper and wiping skids above the water line. A game changer. No brush needed, nor dried on skids

Is he disabled? If not, why does he use the disabled cubicle?

He shouldn't be using the ladies.

Why is he using the female toilet?

personally I think using a brush for skids is fairly disgusting it clings to the bristles

Not disabled, no. I mentioned it to a colleague yesterday without saying name. They replied "(insert name, he has form for it. He goes to the cleanest one"
Oh well done @NoMorePoliticsPlease

@NoMorePoliticsPlease I completely agree. Grim objects
I forgot to add, there are no customers. Place doesn't open until lunchtime

There is only one thing for it.

After he's finished, wait until he's in the main bit of the building, surrounded by people and then yell "Oy Bob, have you left skiddies in the shitter again?"

Use his real name. Don't call him Bob if his name's not Bob.

Ew.

It’s bad enough he does it, but to do it in the FEMALES disabled toilet is just wrong.

Pity you can't lock it up until the place is open for customers. It really is grim and judging by past threads about this sort of thing it's not uncommon.

Wow, I wasnt expecting this to happen frequently. I kinda understand the thing about a clean toilet, but they're all bloody clean ones!! Very strange behaviour from him

Oh yes - these were the threads I was thinking of:

They are in Classics I think. I couldn't believe it when I first read them, but apparently it is a thing - with some men.
