One from the early 1990s I think but some friends used to run a pub and they used to stock Really Ruthless brand crisps. Now usually when you get crisps that claim to be hot or spicy they are only ever just a little so. These Really Ruthless crisps however truly lived up to the name. I seem to remember there was some kind of little red devil on the logo. They came in three flavours if I recall correctly - there was a curry flavour, a chilli flavour and the third, my favourite, was a garlic flavour. They were absolutely eye-wateringly spicy and hot, which I think worked to the benefit of people selling them in pubs, as you needed to drink a substantial amount to nullify the burning sensation. That said I recall we were all addicted to them at the time, as if it were some kind of badge of honour to be able to get throuh a bag without looking like you had been crying. Then one day, we were told by said pub owning friends that they hadn't been able to restock. I think I remember them being stocked in supermarkets but only briefly. I suspect that the severity of the spiciness had been their downfall as they were on the extreme end of the snack market and apart from the wave of interest in terms of "Hey - you have GOT TO TRY these crisps" they were probably too far beyond to the right of the flavour preference distribution curve to be market viable. What a shame, it was lovely to have a choice other than barely flavoursome or mildly spiced. At least there was no question of the trades descriptions act being breached - it was certainly honest branding. If these came back tomorrow I'd buy them by the boxload, if only to enjoy for myself, and...oh go on then, to try to catch people unawares "hey - you have GOT TO TRY these crisps!"
