Nice one Michael!

I'm reminded of another story. My wife took my brother's step-daughter from Belgium to Windsor for the day some years ago. They were changing the guard at the Castle. The Welsh Guards were on public duties at the time. My wife was explaining how you could tell the difference between the various Guards' regiments by the spacing of their buttons, the various insignia (leeks for the taffs, little bombs for the grenadiers) and so on.

They didn't notice that the big taff colour sergeant had been listening to them until he turned around and said to the missus: 'You know a lot about soldiers...'

I'd always suspected as much.
