went out this morning to get caught up a bit.Care home that me and marcus do together then on to finish off some of my stuff (2 houses and tiny bungalow) so ready to start fresh on monday.Get to bungalow which is last job,just get started when old dear comes out ,offers coffee and then reminds me i was going to clear out the gutters((i had forgotten completely) any way not got all gear but improvised quickly with w/c bucket and a borrowed binliner. Two straight runs of guttering ,front and back,stepladder job, check front....empty,check back....empty.I gave her an estimate of 25 to 30 quid before i started but in the end i couldnt do it and said a fiver just so i didnt actually lose out.Is this bad business? am i just not ruthless enough or what?.... 
what would you have done
Depends on a few things really, but i think its not a bad way to go, as long as you dont start to think of yourself as a charity to help all waifs and strays, you can give because you want to, the more successfull you are the more you can give when the feeling or situation arises.
The gutters were clear though, what would you have charged if they had been half full? I presume you based your cleaning figure on how dirty you thought they would be.
