My wife had an automobile failure disaster while travelling through Las Vegas.
We took the vehicle to Monaghan's and were trying to figure out how to solve it. I was asking him questions about the repair because we were very low on funds, and he got really upset and yelled at her "Does your husband want me to tell him how to do his job?"
I had only asked him questions, so I don't know how that qualifies as "telling him how to do his job"
We took our vehicle somewhere else and are very happy about that.
