Did a job for local social housing outfit, they warned me the tenant was "depressed" with learning difficulties, she, sitting on sofa, absolutely refused to move including lifting her feet off the carpet so I cleaned around the sofa, and her feet, it was a real minger too so the unclean area stood out a mile, I charged extra and explained why, received apologies & prompt payment.
At the end of the day we are earning our living cleaning up other peoples pooe, charge the right price and no job is too dirty
