I know a British guy that's a total jerk!
There's this British guy at my job who acts so prim and proper like he would never break any of the rules. But when no one's looking, he's a total self serving, untrustworthy jerk that would stab anyone in the back. I didn't actually notice this until one of the ladies pointed out this behavior to me.
Sometimes when I see him, all I can think of is Jason Isaacs.
