Kit Kat
editMoreover, they did 3 and 5 bars. These came from dedicated vending machines (put in a coin and twist a knob) that we had at school. Really hard to find any info on them and I guess they were only for vending machines. My twin brother definitely remembers three bars but not five. I wasn't a particularly greedy pig but was quite the maths wizz and the five finger ones were cheaper per bat than 2 + 3.
I think they did 6 bars at some point too, called "Kit Kat Way Too Much Fat Boy" or something-- but they were not vending, they were just bigger. I presume the machine can make pretty much any number of bars per ration you just adjust the chopper. Sometimes you get a bar that's obviously been chopped wrongly as it hasn't a chocolate coating on the outside of one side.
