Whenever I'm told I
must wear a hi-viz jacket I follow the letter of the law and I do exactly that.
Sometimes I wear it inside-out, sometimes I wear it back-to-front, sometimes I wear it upside-down, sometimes I wear it with one arm in and one arm out, etc, etc.
If I'm going to look like an idiot in a hi-viz jacket then at least I'll look like a piss-taking idiot.
