Just back.....
As Diamond, assigned to an 8th floor Regency Club room using FFN, even though the hotel mixed up the dates on my arrival.
Quite satisfied with the evening (6-8 pm) and morning (7-11 am) spreads in the Regency Club. Not so fab in the mid-afternoon: cookies and apples only, plus coffee/tea and a number of soft drinks and juices.
Satisfied with the Diamond amenity: full bottle wine (albeit very recent 2003 Cab), extensive fruit, full bottles of both still and sparkling water (also available in lounge).
The staff in RC and elsewhere in Britain can be goofy. It's just part of the culture, as immortalized by John Cleese in his onetime "Fawlty Towers" TV show. And those guys/gals may not be trained to be full concierges - the guy downstairs might - underline, might - be better.
