Many years ago an English lady in Africa was invited by an important local chief to be the first person to use his new bath- the first one in that part of Africa.
The lady went into the bath-house, turned on the taps and got into the nice, warm water. But when she looked up, she was frightened to see an eye watching her through a hole. She got out dressed and ran outside. She saw an old man and a donkey there. He was carrying a petrol tin of hot water in one hand, and one of cold water in the other, and in front of him were two funnels.
“ Why were you watching me in my bath? ” the lady asked him angrily.
The man answered politely,’ I have to see which tap you turn on, madam, or I don’t know whether to pour in hot or cold water.’
