Update:
Boss wasn't in so couldn't hand it in to him! So I went and gave my letter to the General Manager. He was 'Disappointed' but appreciated it was a stressful job and if I wasn't happy then that's the way it is.
Saw my boss the following Monday and again he was disappointed but understood...
I like your style! Unfortunately although I couldn't give a toss about the company, I do give a toss about my team so need to do it right.
I have loads of holiday left so i'll try to use some of that up (i.e next Saturday).
Never resigned from a job before..usually made redundant or 'released' so this will be a first for me.
Have to give a month's notice as well so thing's are going to be a bit 'awkward' for a while.
But I really, really, really, really, really,really, really, really, really, really,really...
