I love the rug brigade too! Did a job just before Christmas, an average size lounge, and the lady asked if I would clean a rug for her which she said herself was in desperate need of a clean. I cleaned the rug first and then went onto the lounge. When I'd finished I got my receipt book out and said "shall we say just £10 for the rug?". Silence. "Err, yes, okay alright". You try walking into Tesco and saying "I've changed my mind I'll just take an extra bottle of wine if you don't mind!"
