In a body shop i used to work at they charged £1500 for 3 hours work so we had a fat argument about it.
I refused to pay it.
I know it was 3 hours cos i was still working there, i striped it and flatted it in my own time all they did was jig it for me.
Plus they under paid me and owed me over £800 so i never paid it but now its all sorted move it monday to get it finished.
