...got mowed down by a van on the ramp at Brussels one night. They were wearing black uniforms.
Horses for courses. Daylight (i.e. the great majority of the time) at a
GA airfield is an entirely different situation.
One thing that grips me is seeing all these GA aircrew wearing the nice flammable bits of dayglo nylon when in the aircraft. Frankly, that seems a hazard they could do without.
