Just before xmas I posted a thread about a stain on a £ 38 k bedroom carpet, well while on that job the Russian caretaker walked up to myself and another contracter who were chatting and joined in our conversation, as though he had been there all along. I later was told, it was not unusual, and to be careful what I said as certain rooms were bugged. You cannot be too careful, and should always treat customers, house and property better than your own. That way they wont have any material to do a carpet cleaners from hell prog.
