charge her m8 im not a tight fooker but my attitude is if u dont do it they would pay someone alot more so even if u charge em half their saving money.

its always hard with friends aswell, i usually charge them half what i charge myself out at work for(which puts em of most of the time) your skilled at what u do and thats why you get paid for it.

Tell em to go and fit it themselves and then they will realise £200 a day isnt so bad to get it done properly and in half the time.
