Wagon wheels and bovril was about all you could buy at the ground in the 70s other than programmes. As a youth I used to relish reading the Iley View whilst eating my wagon wheel and washing it fown with a bovril chaser... ah simpler times...
Proper wagon wheels though not the shrunken version thats sprayed with chocolate. Remember when they did that food/drink counter under Brewery stand in the place where generations had gone for a piss rather than go darn to bogs at bottom.
Those breakfast biscuits that are always half price. Then people walk past and buy them because they are half price. When that is actually the real price but they are constantly marketed as being half price to fool you into buying them. Or summat.
