I get pretty good money on upholstery,don't really enjoy that very much either,but it's really picked up this year, so increased my prices.
Rug wise normally get asked to go over that quickly will you mate , like the last one,the guy said he only wanted a sort of freshen up / light clean, thing is as you know, there is no such thing as a light clean.
Once you wet it it becomes apparent that they are normally filthy.
