Fagash Flo' at Halton would give you a "special" non-reg haircut for a two-bob tip. That was a fair wack of your thirty bob pay, and reserved for "48s", when we were let loose on London for the weekend. Otherwise it was the standard five strokes of the shears and a scissor job on top. The strange thing is, Fagash Flo's handiwork would be the height of fashion these days.
