From all that I have ever read about the operation, it was run in a very old fashioned hierarchical way.
Was it ever!
Loos in Donington Hall with "Directors Only" notices on the door and memos to staff to enforce the rule, speak only if you were spoken to by senior management (who rarely spoke to minions), catering service from the canteen for management
There were exceptions - Austin Reid, for one - but most of the management I had dealings with were so far up themselves that they didn't know whether to f%$t or brush their teeth.
