In somebodies downstairs toilet and you pebble dash the seat, the rim AND the cistern you should either bloody well clean it up or say to your guest "I'm ever so sorry, but I seem to have shat half of the River Nile around your bathroom, I'm now a bit weak, would you mind cleaning it?"
It was not a pleasant experience walking into that this morning and it had been there since yesterday P.M (she was the only one to use that toilet) so it's stuck fast.
And yes I know I should be more sympathetic to people with diarrhoea but a warning would have been nice!!
