If anyone ever offers you a piece of salty liquorice on a return from a weekend in Amsterdam, punch them in the face.

Good old sodium chloride is a bit too mainstream so the freaks use ammonium chloride. The "mmm what an interesting salty/sweet flavour" suddenly deteriorates into "mouthful of bleach and burning sinuses" hell, cue an office full of people retching and spitting into bins.

I think salted liquorice is quite delicious
