Been a long time since i heard this one but it reared its head again today

New customer i quoted via email the other day, window cleaning for a 2 bed terraced plus conny.
Quoted him £14 ,4 weekly.
Did the job, spent ages on it getting it perfect then today got an email....you havent cleaned the conservatory.
Me being baffled i asked for some pics.
Hes only sent pics of the roof

In what world are you going to get a full conny clean and windows for £14 lol told him roof would be £80 not sure its going to go down well this.
