BBC Hausa correspondent Yakubu Liman met Isa Kebbi (left), who sells tiger nuts from a wheel barrow at a market in Abuja. According to Kebbi, he buys a sack of tiger nuts on credit every month and if he make a lot of sales, he makes a profit of around $19 (£13).

He is not the first food seller seen wearing a suit to sell his goods. In 2015, BBC published a photo of Daniel Nartey (right) who wears suits to hawk fruits in Accra, Ghana. He told the correspondent that he started wearing suit to sell watermelon after he was told by his pastor to dress well no matter the job you do.
