basically I priced a job for a guy I said there's about 2 days work for me and lad plus material money which is gonna be x pounds he said fine crack on ,so I went today got it all bonded cleaned up and I was finished for bout 1.30 it went sweet , all ready to skim tomorrow, he has just rang me and said what time will you be done tomorrow so I can pay you I said about 2 same as today he said how much will I owe you then I said what we agreed x pounds but you finished early today he said and looks like you will tomorrow, so what i said if the job had run over time I wouldn't have charged you any more price is the price
