"Of all the cultural matters, the most important to observe in Ghana is what to do when meeting someone whether formally, at work, or informally such as random meetings when traveling.
Ghanaians will always take at least five minutes inquiring about each others’ family, work and health before getting down to business. No matter how pressing the matter at hand, priority is placed on the other person and the family, and there is an obligation to ask after the well being of the others’ family before anything else.
When traveling, if help is needed it is polite to first at least inquire “How are you?” to whomever you meet before asking for the help.
Like many international cultures, shaking is done exclusively with right hands. In Ghana there is an addition to this. In informal or friendly situations the middle fingers are clicked together to make a sharp “snapping” sound. In formal work situations or when meeting elders the snap is left out.
No left hands
Also, like many international cultures it is forbidden to use the left hand for anything of significance. It is reserved for cleaning one’s privates and therefore considered dirty. Do not use the left hand to eat (Ghanaians eat with their right hands), to handle money, to wave, to shake, or in any intereactions with other people."
