"extreme disinfected hanky waver "

I read that first as 'extreme disaffected hanky waver'

BTW, the Folk Police inspector is called, appropriately, Maurice 'Hanky' Hancock.

If you happen to have a Public Hygiene Certificate you don't need to get the offically disinfected hankies - you can get a Morris Hanky Waver Waiver.

(I'll get me coat!)
