I love this moment.  I love it, because Agent Carter she is historically accurate.

American servicemen serving in the UK were issued pamphlets reminding them that the UK women had been in that war longer than the Americans had and deserved their respect:

A British woman officer or non-commissioned officer can and often does give orders to a male private. The men obey smartly and know it is no shame. For British women have proven themselves in this war. They have stuck to their posts near burning ammunition dumps, delivered messages afoot after their motorcycles have been blasted from under them. They have pulled aviators from burning planes. They have died at the gun posts and as they fell another girl has stepped directly into the position and “carried on.” There is not a single record in this war of any British woman in uniformed service quitting her post or failing in her duty under fire.

Now you understand why British soldiers respect the women in uniform. They have won the right to the utmost respect. When you see a girl in khaki or air-force blue with a bit of ribbon on her tunic - remember she didn’t get it for knitting more socks than anyone else in Ipswich.

No wonder she decks him. And no wonder his boss believes he deserves it.
