yes I know where that is.....regards having my customers, they arent mine, they are everyones, I just go and get them......that was one hotel in London, how many more do you think there are??...400m in a day isnt that much carpet to clean.....The reason they paid what they did is that they had paid 3 other times to have it cleaned with no satisfactory results. I cleaned it for a little more than it would normally cost because I was following a non extraction cleaner (s) so had to clean their residue out before I could clean it, we will say a different way....best, Dave.
