classic ! haha my mate bought a boiler for B&Q 2 year ago, changed the pcb twice already !"Ill do all the rads and pipe work and even hang the boiler" and you just connect the gas, CHEERS, BUT NO THANKS ON THAT ONE.
"Can we knock some off for labour if I take the week off work and help you" work,.
"I used to be a hydrolics engineer at the turnip factory back in the 1970s, therefore I know all about plumbing and Iam going to watch everything you do" work.
"Ive got the boiler from B and Q weve had a quote from daves brother in laws mate to fit it for £10, so can you fit it wednesday" work.
if anyone ever says "how much is this going to cost because im quite skint" then just tell them you won't be able to afford my services then !
I also hate people who hover over you watching your every move asking questions etc
