comment
it invites a reply and my reply to that was ,because you want to make a living cleaning carpets, your not doing it for nothing or out of the goodness of your heart, sorry to be negative because apart from that it looks brilliant i just think it patronises the customer, and may p them off.
i am no pro carpet cleaner or marketing expert it just my humble oppinion, if that come through my door thats what i would think.
