I cleaned a flat in a nice area, and noticed the entrance to the communal area was rather dirty. I spilled some powerburst on the way out, and had to rinse it out. This left a nice clean square, in the middle of the carpet. Put some leaflets through the doors, and got a call today saying I had ruined the carpet and when was I putting it right. By ruining, she meant it was clean and didn`t fit in with the dirty surrounds, and I should call round and clean the full carpet, to make it match, for free. I gave her a price, and she said she would run it by the commitee. Should I have cleaned it for free, or should I wait and charge.........that is the question.
