make sure you take sum 1 with you and smack the bastard.i worked for sum guy for nearly 4 years and he used to piss me about every week with money but i needed to learn the trade off him,so stuck at it didnt want 2 but did,and as soon as i could do it on my own i left him but still did bits of jobs for him but still tried to take the piss with money.i did a kitchen before christmas and when it came to get my money he said he didnt have it so me and my mate had word with him said if he didnt sort it out we would batter him funnily enough he rang me the next day and gave it me.people like this need sorting out
