Done a first clean,with gutters fascias,spent 2 hours ,looking like New as they were green,customer comes out with paper with all windows listed and has marked I missed a corner and left dirt there,well I checked and its grease fron rubber seal ,I said you need a toothbrush to get that totally removed ,as that's a result of years of neglect,honestly its about 1 ml of grease can only see it if you search ,I explained how dissapointed I was as the house now looks like new and he searched for a tiny fault,I then explained I would offer a premium service at 4 times the cost and would require all the plants trimmed and dog poop cleared before I could get a scaffold tower in,also would need new hose as mine covered in spectacular dog s..t ,he then mentioned he was happy and see me in 6 weeks ,I mean Wtf,,,,why are some people like that it makes me feel like crap.
