Thanks Anita.

I would not mind kindly letting him know, except, management has already spoken to him about it and they said he did not take it very well. He is not very friendly to begin with (never says hello) so I do not feel comfortable talking to him about something that he already knows is a problem, but doesn’t care. I’m also afraid of retaliation. He may get pissed off and just rev the engine even louder and longer.

Thank you for the suggestion. I know if anyone ever came to me and said something I was doing was bothering them, I would feel terrible and do everything in my power to fix the problem. Unfortunately, not everyone is like that 🙁
