Fading
The few searches for it in Perth are under half their 12-month high, and cafes are not picking it up: too few of the same cafes have it to read a change (2, against 3 in the 90 days before).
No cafe had it in the last 90 days, or the number of the same cafes with it fell by a quarter or more on the 90 days before (from at least 10 cafes) while searches did not rise, or searches are under half their 12-month high and cafes are not picking it up.
The stages run Emerging, Rising, Peaking, Mainstream, Fading. A trend can skip a stage or move back.
