On 'Mini's there were certain Captains who only spoke to the Cabin Crew through the First Officer. "Would you ask the Captain what he would like to order from the menu" This of course was before CRM. There was also a certain Captain nicked named 'The Blade' who wore white gloves and would run his finger along the armrests of first class. Woe betide the crew if his gloves were dirty! That of course was before slots!
I believe the 747 help do away with all that.
