Well, its not been often recently that dear old Kodachrome processing in Europe comes in for praise, so I'll say something...
Six callendar days, UK to Switzerland and return (posted Tuesday back on Monday) is pretty much back to how it was before the move from Wimbledon. This is not un-typical now, from what I understand from other K64 users. And just before that, 49 films sent, 49 films back, and no noticable processing problems that I've become aware of so far.
Maybe things are a-changing?
