I don’t insult every dealer employee as often as possible - only you! I know it gets to you more than most and love ruining your afternoon!!!Very rare for the tcase seal to be leaking let alone at 400 miles, he's not wrong. Asking if you have done anything is wrong, why would a service manager suspect something had been done? It's an easy $100-150 in his department's pocket. I'm not really sure why you have to insult every dealer employee that way. Be in their shoes for 1 day. For most dealership employees it would be difficult to keep up on every tsb, service trend and specs on every vehicle they have come in.
