Although the word Request has been retained, Compulsory melted away
some years ago, so I have used Red and White instead!

Walking along Widmore Road in Bromley today I noticed (how sad am I)
that I was passing a White bus stop, although the one on the other
side was Red. How common is this and why would it be done on what is a
fairly ordinary residential/A Road?
I also noticed that the White stop was the second one in a row I had
passed. I thought, outside central London at least, they were at least
alternated? Are there any rules about what colour is chosen?
