Here is something else that really gets me annoyed. I am a Yoruba man and know for a fact that an overwhelming majority of Yoruba people will not sell you table salt at night if you call it by its name in the Yoruba language (Iyo). Some will reluctantly sell it to you if you call it (Isebe) which is a name that has been given to salt to get around this unnecessary ban we have placed on ourselves. The reason for this is that they claim that they do not want you to carry away "the sweetness of their life away" at night.
I know this is superstition but the way my people hold-on to it is annoying to say the least. I am sure they would not have a problem selling "iyo" to me at night if I would pay N100,000 for a N50 bag, so why hold on to such obviously ridiculous beliefs.
