The Ale-Conner in the Medieval period had the responsibility of ensuring that brewers of ale did right by buyers of ale. There was a whole thing, and any brewer of ale who didn't follow the somewhat loose leaf rules could be subject to ridicule by being made to 'go play Bo-Peep in the nut-cracker.' The 'nut-cracker' was a pillory.
Bo-Peep, while familiar as a character in the nursery rhyme, was also a name
used to describe excise men in the South East of England. As well there is a
Bo-Peep junction on the southern railways in the United Kingdom. It wasn't named
after a shepherdess, and there was a time when I thought it was.
