Started this house a few months back, nice size £20 without conny, the lady asked for a price for the conny roof and the windows/gutters. I looked at it and didnt know what to say, i dont do conny roofs ever, i dont advertise i do either to my customers but i decided to as i had never seen one quite so BIG before, so i said £100 and forgot about it. So last sunday i text her that i will be coming monday morning to clean windows and she says great, can u also do conny this week, i thought oh no, dont really want to do that thing, but i said ok if i get time. I thought it will only take a few hours (dont usually clean them and dont really know how much efforts involved) Took me 5 solid hours and i woke up with all sorts of aches Now £100 quid is £100 but how much should it have been? So i know for next time im feeling stupid.
