This may sound like an odd question, but is it possible for others to pick up on our PLs? For example, I was in a shop the other day and the lady behind the counter saw the sweetheart brooches on my collar and asked me which regiments they were for (they're Bedfordshire and Machine Gun Corp), at which she said 'oh...the Artillery, thats the word I was looking for!'. There was a queue building up, so I had to leave, but was smiling all the way back to the office. But it got me wondering, could she have picked up on my PL in the Royal Artillery, which led to her thinking to say that regiment? Is it possible that some people, being more 'in-tune' or 'psychic' than others can pick up on our PLs, especially the ones that are very close to the surface?
