My take also. A gentleman never refuses a womans hand, no matter how despicable and disgusting she is.

A gentleman never refuses a LADIES hand. She's no lady.

The "lady" is a tramp!

I’m not sure he saw her hand. IMO, she probably timed it so that he wouldn’t see it and then it would look like “big bad man is mad and wouldn’t shake poor lady’s hand”
