Most People do not have this knowledge,reason their business collapse, especially my tribe ,Yoruba. Yourba will look at igbo people learning how to sell foodstuffs and provision like a wasted time and effort,they feel like what is there to learn about it since you understand the currency, they don't know business is more than just understanding currency every business no matter how little got technics, that's why igbo people succeed in their business, then Yoruba People think igbo people always have illegal business under. There was a woman who has shop beside my sister's shop then, she opened her shop and brought a car full of bread not big ones ooo, the small quantity like 200, 300,500 is the biggest , her shop was full of bread. The first day, she closed by 5pm and went home, I was thinking maybe she has something to do ,the second day the same thing,the third day as well, I began to wonder what she was doing,bread still full in her shop . I was like ,who sells bread and close by 5, who close shop everyday with same bread in it and expect people to buy. Indeed,she did not have any idea about what she wants to sell, at the end she later fold up and move out . She didn't even use a year she paid for. Imagine . Yea, thanks for sharing
