I have bouts of irritable bowel syndrome brought on by stress. When staying with a newish boyfriend who had recently moved, years ago, on my morning visit to the loo I delivered an expolosive mess of sh**t that the flush barely touched. There was no loo brush, and friend was egging me on to be ready for a shopping trip to buy necessities for the house, ( such as a bed!). I mentioned loo brush and kept my eyes open but we didn’t go near anywhere that sold one. When we got back I rushed to the loo and did my best with tissues and water but as it was dried I couldn’t get it clean. When friend went to the loo he said no wonder you wanted to buy a loo brush!
Nowadays I would always have wet wipes on me which if all else fails I could use ( but not flush), but nowhere near as hygienic for the user as a brush. If it is regularly soaked in a strong bleach mix it has to be safer than having to get hands on! Imagine leaving a mess for the cleaner/ owner to clean up. I would give the job to whoever came up with this rule.
