So you are sitting in a meeting with your new boss. Learning lots of things that you need to know. Asking all the right questions. Taking notes and learning the ropes.
You stop to take a break. Get a drink, use the restroom, blow your nose.
After the break you get back to business and you notice a little something not right. There is a "bat in the boss's cave".
What do you do? Stop and tell him? Ignore it?
I'll let you know how it turned out after you tell me what you would do.
