Yep some are not used to regular washing routines and yes some would have a problem opening shower gel as some don't use them to wash with like i have found they just splash a bit of water on them.

I'm often surprised at how smart some are and how completely stupid others are!
Can't or won't read and don't listen to parking information
How  do they function in their daily life 

Aha yes KBP, I can relate with Radox shower gel  I personally have a selection of 3 different shower gels in the shower so clients can choose and the Radox one is always the one that has been barely used when the other ones are almost empty.

I also always show clients how to turn on the shower before they jump in it and let them know not to pull the shower curtain too hard (I've already had someone breaking it by pulling it too hard) and I still get people who call me afterwards because they can't turn it on or try to turn it on so brutally that it would almost break the shower.
So yes some people are genuinely stupid but I would say most of them don't listen and like everything else, since it's not their place, they don't care about breaking/damaging stuff because at the end of the day, it's not them who is gonna pay for the repair cost afterwards 

Yes they definitely are, especially when their eager cock is in the driving seat. Yesterday doing hotel incalls I told a client there was a grey towel for him to use after his shower. A nice clean fluffy grey towel right there on the side of the bath. I also said the bath was slippery so advised he put the white flannel on the floor of the bath so he could stand without sliding about.
Two minutes later he emerged from the bathroom wrapped in a large white towel. Having hidden mine previously, I asked where he'd got it from. He'd picked it up off the floor from among the pile of rolled up used hotel towels that I'd stashed under the sink.
And the large fluffy grey towel? He'd put it on the floor of the bath to use as a bath mat while showering 

Oh yes!  The towel issue.

I've lost count of the number of times I've shown them a clean white towel and they used an old dirty one hanging up.

Clueless, absolutely clueless.

Oh yes ahahaha this one is something, they have a pile of nice large clean towels and they end up using the extra small hand damp towel hanging there, this one always kills me ahahahah and then when you tell them that they've used the hand towel, they look at me like "ewwww, who has used the hand towel before me?" 
Stupidity level 1000

oh nooo, that's terrible, I still don't understand how would someone feel comfortable enough to do this is a stranger's place and where on earth would you even leave stains !!! People are seriously disrespectful and disgusting sometimes....

😩 Dread to imagine what state his own loo is in !

I’d take stupidity over disrespect. A recent client, who I’ve seen before, finished and then had a shower. Didn’t ask. Just walked in there. Flooded the bathroom and bath mat(which wasn’t even on the floor). Then dumped his damp towel on the bed while getting dressed then left. The cherry on the cake was him discussing all the things he’s spent money on lately including holidays and sending his kids to private education. Mone,
As the old saying goes, can’t buy manners.   
He’s an odd one as he can be very helpful in regards to business  advice (general business not escorting) but in other ways is just hugely disrespectful.

That's hugely disrespectful.
I had one actually crack my shower tray because he was so fat but he never even owned up to it.

I don't work from home anymore as they generally have no respect for our stuff.

My hotel bathroom was like an aqua park yesterday. They all just splash water everywhere.
