Having alighted a train at Waterloo station I was on my way to work on the Lambeth road when I was stopped in the street by two strangers who said to me,
"Excuse me do you know where Waterloo is. In reply I said Indeed I do
Its a big muddy battle field in Belgium. They looked at first quite bewildered then it sank in and they laughed like hell Great to cheer folk up. I Then directed them properly.

I answered the same question in the same way a couple of years back
in the work place and the person complained to management and I ended up on a diciplinary. Which was thrown out and replaced with a verbal warning. ain't folk funny ?
