The people are very hospitable, usually they slaughter a chicken as part of welcoming a visitor. Most would be offended if a person refused to have a meal with them, if one insists that they are satisfied, the best approach is to eat very little. Complete refusal to eat their food might give them a picture that you are stingy so you yourself want them also to refuse to eat when they visit you or you suspect that they may have included medicine in the food "(Ukukutegha)".
