Worker learns his lesson when he finds out who the old man he has been pestering really is 

The janitor’s morning

The elderly man had no idea what was in store for him. He was just doing the job he was hired to do. Throughout the morning, he had enjoyed a warm reception from the people working at the office. Some stopped for a chat, interested to know why an old man like him had decided to take up the job. One of the office workers even brought him a steaming mug filled with coffee.

A great start to his first day. Until he met Jeffrey.
