I remember being at a big County Fair where the Irish Guards took a prominent part in proceedings...band, climbing wall, recruitment, target practice etc.
I was with a male friend who decided to challenge me on the target range.
The guns were loaded and my friend did a creditable job then it was my turn.
I scored three in the heart and the Irish Guardsmen asked if I wanted to sign up...jokingly.
My companion merely looked disgusted and addressed him as sonny, telling him to mind his mouth etc.
Of course, the poor guardsmen had no idea that my friend was a Colour Sgt in the Grenadiers which has always ranked as superior to the others, even the Coldstream, although I have 'founded' 5 yrs later.
There is a lot of rivalry between regiments.
