I have a related but inverse question from on observed conversation: As I was picking up my kiddo at daycare, another couple (or unrelated two people? wasn't sure): gal was in basic looking camo fatigues, from the conversation I gleaned she was in the service currently but off duty on her way home. 400lb black dude started flipping out that she was breaking the law and his something or other chewed him a new one for wearing his uniform off duty in the past. (not aggressive, just assertive). So my question is: is there anything wrong with an active serviceperson wearing their uniform off-duty?
