It's probably talking about a door to the building that is an entrance only. Since you're inside the building, you should not go through the door that is for people going into the building from the outside, AKA the "Entrance". Instead you should go through the door that is for people going outside from in the building, AKA the "Exit".

"Excuse me, where's the entrance?"
"Yes."

Reads like an ancient inspirational proverb about thinking outside the box.
