How man rooms were you doing a day . 12 thats amazing did you move furniture . what happened when you hit a dirty carpet.
name and shame the company  you owe them nothing
If I did 5 jobs in a day, I might have 1 room, then 2 rooms and a 3 piece, then 2 bedrooms, then a hall, stairs landing, lounge, then a through lounge with Scotchguard plus curtains, just as a random selection from memory.  It wasn't just banging out 12 rooms a day, the jobs varied.  They usually allowed about 2.5 - 3 hours per job, inc travel, they certainly made you sweat, and parking in town centres was a nightmare at times.   I sometimes travelled within the same town, and sometimes over a long distance, say 20 miles between jobs.  I learnt a lot about what I was capable of work wise, how fast I could move if I had to and what sort of s*** I could put up with for a few quid.  I had to move furniture, but quite often, unless it was a little old lady on her own, they had already moved a lot of stuff, and hoovered as well, which made things a bit easier. Quite a few EOT's as well.  Really dirty carpets were usually allowed for timewise, but, as you probably know, going into a job from a phone quote will sometimes spring a nasty surprise.  One person's idea of  "a small stain"  is a bit different from someone elses.   Then of course, there's always the "could you just..."! 
I'll think about the naming and shaming, maybe another time.  I did do it, but edited it out after posting, some of you may have seen it. 
To Robertphil:-  Thanks for the offer, but I want to concentrate on carpets for now.  I think youre in Suffolk as well, a bit far from me.
