I used to subcontract to a very well known power company (hint Scotland and south of England).
Whilst having to go into the admin offices of one of their depots which happened rarely, I got a very red faced vein popping suit having a go.
I was in Power Distribution offices and my hi-viz scrounged years ago had Enterprise on it.
Which is another arm of the same outfit.
Apparently I was cross contaminating company interests.
I kid not
