I'm not sure if setting up in reception areas is such a good idea. It's basically an arbitrary decision by some manager, but it could just as well be rescinded by another - and for no real reason. My recommendation: scout the industrial estates around your location. The "busy" ones will most certainly have either a permanent or mobile sarney outfit somewhere, or maybe even two. That's where you set up, because folks are going to have to wait in the queue anyway, so they can catch a quick shine while they're at it.
In my initial enquiries my attire was very smart casual. Trousers with razor sharp crease sharper than a woman's tongue, regimental polo shirt and shoes that could blind you from 30 pages.
When it comes to dealing with management though I shall not wear anything related to the army apart from my veteran pin badge on my jacket. After all I'm in Luton which we all know is an active recruitment area for angry men who hate the British military. Most security guards come under 3 headings.
The older retired squaddie who will help in every way he can.
The young guard with bulled boots that joined up but never finished basic. They are easy to spot.
Lastly is the ethnic guard, doing his job and avoiding politics and religion where possible.
