Go on, I'm buying

I'd only been in the job a week and I was late.
I apologised and had to fill out a form explaining why I wasn't there on time.
Later that day, the headmaster called me to his office for a chat.
"It's not just about good timekeeping," he explained, "There's the question of the impact it has on the students. You are a member of staff, and as such, you set an example to the children. They look up to you and will be influenced by your behaviour."
As he was talking, a group of boys walked past the open door of the office.
"There's that spacka being told off by the teacher," one of them said.
"Yeah, let's flush his head down the shitter," said another.
