It's a funny thing is that, Raggytash. I did an idle, back of fag packet calculation a year or two ago concerning the price of a pint as compared with income. When I started teaching in London in 1973 a pint of G in Chelsea cost three bob, fifteen pence. I worked out that it was quite a bit dearer in real terms then than it is now. Don't ask me the details. I might been doing it alongside teachers' pay. Can't remember.
