I remember as a kid being at a military parade in Scotland.It's called the "Edinburgh Tattoo" and it's held yearly.
Thisyear it was raining ,cats and dogs,buckets, and sheets of rain.
The Tattoo went ahead but all the personnel were in rain gear,taking away from the spectacle.
The Gurkhas were marchng and marched in full dress uniform saying that if the people who had come to see them were prepared to sit in the rain to watch them the least they could do was to perform to the full for them.
I could imagine cleaning their kit afterwards would have taken days.Wonderful,and the Gurkhas marching took that decision themselves they weren't ordered to.Don't mess with the Gurkhas.
