All the staff you interact with have been to the same handful of British public schools (ie private fee schools) so you never have to talk to someone who is ignorant of precisely your standing in the British class system and they will all speak with comforting RP, follow the cricket, and drop an occasional Latin phrase into the conversation. Banking service is basically as shite as all the rest. [source: I ran a company that for very strange reasons ended up having to use them for business banking services]
