I haven't experienced enforced armbands either, Jim. But I have experienced wristbands that All-Inclusive guests are issued with - not in the UK hotels I've stayed in, but definitely in Greek/Corfian/Cypriot/Cretan hotels. In all honesty, I can't swear that wearing those is compulsory, but they are very definitely issued for ease of identification of A-I guests in the restaurants, bars and other hotel facilities.

So, if your nemesis hasn't specifically mentioned wristbands being used in UK hotels, why do you keep prattling on interminably about them in UK hotels - presumably it's a manifestation of your OCD where he's concerned? (To be fair, I think he's also OCD where you're concerned, so you're both as bad as one another AFAIC).

BUT....I completely agree with you in respect of the humiliation and abuse of immigrants/asylum-seekers, and I'm convinced that a simple card similar to a driving licence or buss-pass is a suitable solution.
