My, how things have changed. Years ago I worked at an electric board. All the meter readers were white with just one, a large Jamaican chap, same colour as the ace of spades. They all had nicknames, his was bin liner,and no, he was not offended, just amused.
One day at lunch one of the readers says that Mrs so and so such at one address was not left a receipt after her slot meter was emptied.
She said "it was a big black chap" To which our Jamaican friend in his superb accent said " How do know it was me"
Happy innocent inoffensive days.
