I had one the other week.
nothing big it was just a standard very small 3 bed semi and give my price of £8.00 and she said oh ok! my last window cleaner was 3.50 and all i said was oh was he! anyway she agree's i said ok i will be round such and such a day between 1-3pm..
So this day comes and i was running slightly late ended up getting there about 3.30 but 2pm come and my phone rings she says - are you still coming?? I really need them cleaning you are going to turn up arnt u??
So i said yes just running abit late shouldnt be long get there shes not in. She id say on phone she mite have to pic her child up fine i thought, halfway done she comes home and says o thanks.. do you want paying today?? just i havent got any the money on me.
She new i was coming that day it was a first clean...

really anoyed me it was only 8.00 but thats not the point.
