Time passes but some things never change, such as the atrocious table manners of characters in American movies.
The more wealthy and sophisticated they are supposed to be - like this couple in 1993's Sliver - the worse it seems to get...forks held in the wrong hand, stabbing almost sorrowfully at the contents of the plate.
And in this scene it is the knickerless Sharon Stone who is supposed to be causing a stir.
Even George Clooney does it. I bet Amal can barely bring herself to watch, thinking thoughts along the lines of 'Where was you brung up...the workhouse?'
