Well done my first commercial job today took me twice as long as anticipated they were minging i tell ya . 5 hrs solid i was on it but spoke to the gaffer after as he tried to get me to do something that wasnt in the quote . I said that it wasnt included etc so he said ok bill me more for this first clean say £150.00 and and the next clean with the extra 5 windows i will give you £110 . Lol so a £90.00 job im getting paid £160 and the £90.00 job has turned into £110 ha ha . So a happy chappy all round .
