Ahh the fun of pilots uniforms = security guard. I was in Sainsburies the other day, when someone got annoyed with me and a few other pilots with me because we couldn't tell him where the charcoal was. When we said "sorry we don't work here.' he looked confused for a while, then angrily stated "What are you doing here then!" Shopping....
My course partner and I decided to rebel against the need to dress up like security guards during our CPL/ME/IR, so we purchased and wore the "security" epaulettes.
