The parking attendant at TRA (Tanzania Revenue Authority) was looking very dour and grumpy. I tried to be extra nice to her. 'Pole na kazi. Pole na jua kali'. Sorry about your work (doesn't translate quite as well but a common saying) sorry about the sun. How are you, how is home?' She thawed ever so slightly.
'What's that on your sleeve?' she asked 'Looks like a bird shat on you'
'Yes, they say its good luck'
She laughed 'Whoever told you that is a fool!'
