Anyone experience less stuttering when in a uniform and talking to strangers?

Anyone experience less stuttering when in a uniform and talking to strangers? Hey folks, long time lurker. I'm currently in my second year as a student radiographer in Denmark, I'm currently in the second week of my 8 week clinic (2nd clinic). One thing I've realised in this and in my hobbies (roman reenactment and first aid), I've noticed I stutter less with patients and strangers when I'm wearing a uniform. Anyone else experienced this?
