Literally NOBODY called Adam by his last name, and the ONLY person hes heard call him Mr. Ross in YEARS was Sid Hammerback. He wasnt really into formalities, nor did he like the Yes sir, no sir because he grew up with it being a strict rule that made him dislike it. But when you came along? You used formalities and Yes ma'ams and No sirs. When you walked in the first day, you said "Good morning, Sir." Briefly on the way to your desk which flabbergasted him.

"W-What did you just say?" He stammers, taken aback.
