“Say Again”
If a person says “say again” rather than “excuse me” or “pardon me”, then they are probably a soldier. After serving in the military, this habit will still follow them in civilian life.
Finding The Exits
Soldiers learn from training to make sure that they know where the possible exit points are as soon as they walk into a situation. A soldier will keep this habit for their whole life and you can be sure that he will know all the possible exits.
