Happy St. PADDY"S Day!

I thought Grammarly was wrong about this, no one writes St. Patty's, but I saw a sign in a medical lab this morning that read, "Happy St. Patty's Day!" When I pointed out St. Paddy was spelled wrong an employee said, "At least they get an A for effort." No, no, they don't. You get an A for excellent work and a F for getting it wrong and then not correcting your mistake.
