Clowns or little blue men , I wouldn't listen to either of them.
I was asked by a walk up to clean 2 flats, a first and ground floor. Whilst cleaning them the basement owner returned home and went ballistic not because of the windows but because of plants ffs even though I apologised for upsetting him explained just water, no soap etc. asked if he would like me to stop ? he launched in to a verbally aggressive assault on me, I had to leave jobs half done and give payment back. I very nearly lost my cool but glad now I didn't.
Although at the time I did think about going back late at night after the pub to 'water' his plants for him.
