Stop in for a cup of coffee

One of our engineers has a saying. "Piss poor planing on your part doesnt constitute an emergency on mine"
Yup, Did the manager thing before. Not my spot where I am now.
I'm just a maint tech. I normally prioritize whatever jobs are up on the counter and just do them. But, when they start bustin stuff up and presses go down, I tell the supervisor "I'm here till 11. What do you want me to do?
