Had a custy who wanted in and out for £20. Cleaned once and cleaned outside the second time and said to myself no way am I cleaning this for a tenner. So dumped them about 6 months ago. Just got a call... Hello you come clean my windows... You charge 20 and you clean inside and out.. Me what's tour address. Ohh no I stopped because it was too cheap. It will cost 14 for outside and qr for inside... No its 20. Me - no its 30 for inside and out. You where to cheap. OK you come. OK Tuesday. OK Me- and its 30 I don't want to barter for money... Lol you only do this after you've had shxt for 2 years and are classed as a veteran windy and start putting your foot down and stop being walked over.
